&nnmary-This study tested the hypothesis that cooperativeness is a cause of happiness. 114 Ss were given
a 36-item scale for cooperativeness, together with measures of happiness, extraversion, neuroticism, MHQ,
COMQ, and other scales. This was repeated 6 months later. In a multiple regression analysis happiness
at Time 2 was predicted by one factor of the cooperation scale which was interpreted as enjoying group
leisure activities. This factor also discriminated Ss initially low in happiness who became happier; those
who started happy and became less so were low on another dimension of cooperativeness-interpreted
as enjoying joint activities at work. Happiness was also predicted by extraversion, (low) mental health
(MHQ), and age (youth). Mental health correlated negatively with cooperation, but was not predicted
by it; it had a two-directional relationship with happiness. The total cooperative score was predicted by
extraversion and sex (female), and the cooperative over leisure factor was predicted by sex and social skills
KQMQ).
INTRODUCTION
In a previous study (Argyle & Lu, 1990a) we found that extraversion correlates with happiness
partly because extraverts engage more in two kinds of social activity-teams and clubs, parties and
dances. In a second paper, using a longitudinal design, we found that a further explanation for
the greater happiness of extraverts is their assertiveness (Argyle & Lu, 1990b). The findings of the
first study suggest that the cooperative activities and hence the cooperative skills, of extraverts may
be important for happiness.
What exactly is meant by “cooperation “? Dictionaries define it as “working together”, social
psychologists refer to shared or group goals. However these definitions emphasize rewards for joint
work towards external rewards, and do not readily include some clearly cooperative activities,
which cannot be performed alone, and where competition would often be irrelevant, like playing
on a see-saw, dancing, making music, sexual intercourse, playing tennis and conversation.
There are perhaps four main classes of cooperation-joint task activity, social relationships,
coordination over joint activities, communication and interaction.
Here is an attempt at a revised definition.
Cooperation: acting together, in a coordinated way at work, leisure, or in social relationships, in
the pursuit of shared goals, the enjoyment of the joint activity, or simply furthering the
relationship (Argyle, 199 1).
Cooperation is found in all species of animals, in varying degrees, and several evolutionary
models have been put forward to account for it. It follows from evolutionary theory that when
a behaviour pattern serves long-term goals, shorter-term rewards will develop to provide
appropriate motivation. For example, the joys of sex motivate reproduction. Cooperation of other
kinds leads to the important goals of mutual help and social integration; it follows that there should
be short-term rewards, that cooperation should lead to positive emotions and to happiness.
There is evidence that cooperation has certain positive consequences-mutual help and
interpersonal attraction (Deutsch, 1949). Happiness and mental health are enhanced by compan-
ionship and social support; such social activities require cooperation and coordination of
behaviour. Activities with friends are one of the main sources of joy (Scherer, Wallbott &
Summerfield, 1986). An important part of social support is cooperating in joint activities, being
embedded in the activities of a social group. Examples are dancing, music, games, and other leisure
activities of friends, and also, we shall suggest conversation. Research on helping behaviour finds
that people often react negatively to being helped, and that cooperation produces more positive
reactions (Worchel, 1979).

In these cases there is no product, and the goal is the joint performance as an end in itself (Argyle,
1991). In the case of close relationships there does not appear to be any goal in the sense of seeking
rewards, but rather both partners are seeking the goal of a close relationship, and are concerned
with the welfare of the other (Clark & Reis, 1989). For work there is division of labour, and job
satisfaction is higher in cooperative groups (Argyle, 1991). Families can be regarded as groups
devoted to biological cooperation over eating, child-rearing and mutual care. Conversation, and
social interaction of all kinds, require a high degree of cooperation, in terms of the synchronising
of utterances and keeping to social rules.
It was also expected that cooperation would benefit mental health, in view of the well-confirmed
research showing the effects of social support on mental health. While support from an intimate
has been shown to be important, recent studies have found that the social network is also
important. This is supported by Rook (1987), who found that companionship had a greater effect
on reducing loneliness, and enhancing psychological well-being, than emotional or instrumental
support.
Individual differences research has so far not produced an accepted measure of cooperativeness.
Ratings have been used for example for children playing. The Prisoners’ Dilemma Game and other
experimental games, offer a choice between cooperation, competition and sometimes altruism and
individualism (Liebrand & McClintock, 1988), but the validity of these games is very doubtful. No
dimension of cooperativeness has been located, but in research on the “big five”, “coopera-
tive-negativistic” falls under the wider factor of “agreeableness” (Norman, 1963).
Some better-known scales and dimensions have been found to correlate with observed
cooperative behaviour. Crandall’s “social interest” scale is about being concerned about other
people, including cooperation, sharing and helping. It comes very close to being a measure of
cooperativeness. It correlates with cooperating in the Prisoners’ Dilemma Game, ratings of
cooperativeness by peers, and negatively with hostility and self-centredness (Crandall, 1980).
Social competence is often assumed to include cooperativeness, and lack of cooperativeness is
regarded as unskilled (Dodge, 1985). McPhail (1967) compiled a list of common social problem
situations encountered by adolescents. He found that the number of socially skilled solutions, where
the needs of both sides were considered, increased rapidly between the ages of 12 and 17. Research
on child language has obtained similar results. By the ages 14-15 most children use arguments to
persuade others, in which they show how it is in the other’s interests to do what is suggested.
Extraverts are cooperative in various ways, for example rating cooperative situations as likeable
and rewarding (Wolfe & Krasner, 1988). As we saw earlier, they take part in cooperative activities
like teams and clubs. They are good at cooperating in ordinary social situations by asking
questions, agreeing and paying compliments (Thorne, 1987).
Neuroticism is expected to be negatively related to cooperation, because neurotics tend to be
egocentric, taking little interest in the concerns of others (Trower, Bryant & Argyle, 1978).
Internal control is another possible predictor of cooperation. Those high on this variable are
found to be happier, and believe that they can control events in which other people are involved
(Phares, 1976). Such control is only possible with skilled cooperation.
Self esteem is a strong correlate of happiness. The interpersonal style of high esteem people is
certainly distinctive, and it would well indicate the confidence and concern for others needed for
cooperation.
“Collectivism” is a related concept, referring to the sharing of resources and outcomes with the
immediate group, as found in Chinese culture (Hui & Triandis, 1986). Individuals with high scores
on collectivism have been found to be less lonely and to receive more social support (Triandis,
Bontempo, Villareal, Asai & Lucca, 1988).
There is evidence that women are on average more cooperative than men. Studies of children’s
play find that girls are more cooperative, boys more competitive (Knight & Chao, 1989). At the
Prisoners’ Dilemma Game women are less cooperative, but this is usually interpreted in terms of
being less risky (Colman, 1982), and in social dilemmas with real money women are a little more
cooperative (Stockard, Van de Kragt & Dodge, 1988). Women have much higher scores on
empathy (Eisenberg & Miller, 1987). Women’s groups are more egalitarian and cooperative. In
groups which initially do not have leaders, men more often emerge as overall leaders, but women
more often emerge as social leaders or “facilitators” (Eagley, 1990). In research on assertiveness
Happiness and cooperation 1021
it is also found that women are much more concerned with obligations to others. They think that
it is important in assertive situations not to threaten others, to be friendly, and not to hurt others’
feelings (Wilson, 1989).
Analysis of conversation finds that women are active in keeping conversation going, ask more
questions, use more tag-questions, give more back-channel responses, and are more polite. Female
social interactions appear to be directed towards the goals of friendship and social support (Smith,
1985; Argyle, 1991).
What exactly does cooperativeness consist of? There are probably several components.
(1) Competence-the ability to integrate the goals and ideas of different people, and find a common
plan.
(2) Values-a preference for the cooperative mode, enjoying cooperation.
(3) Rules-believing that cooperation is the right way to do things.
These three aspects were incorporated in our 50-item questionnaire, which also covered 8 spheres
of possible cooperation.
METHOD
Subjects
114 subjects from the Oxford Subject Panel took part in this study. The sample was composed
of 42 males and 72 females, ages ranging from 18 to 65, with a mean of 44.1. There was no age
difference between the two sexes.
Procedure
This study adopted a longitudinal design, and data were collected at two sessions with a 6 months
interval from the above mentioned sample. The Time 1 questionnaires were sent out in March 1990,
which contained measurements of happiness, mental health, cooperativeness, and various person-
ality inventories (see the next section for a more detailed description). The Time 2 questionnaires
were sent out in September 1990, which measured happiness, mental health, and cooperativeness
again.
Measurements
(1) Happiness was measured by the Oxford Happiness Inventory (OHI) (Argyle, Martin &
Crossland, 1989).
(2) Mental health was measured by the Middlesex Hospital Questionnaire (MHQ) (Crown & Crisp,
1979). The MHQ gives a total symptoms score and four subscale scores: depression, anxiety,
obsessional symptoms, and somatic symptoms.
(3) Self-esteem was measured by Rosenberg’s self evaluating scale (1965).
(4) Social skills were measured by the COMQ (Sarason, Sarason, Hacker & Basham, 1985).
(5) Assertiveness was measured by Gambrill Assertion Inventory (Gambrill & Richey, 1975). This
scale gives two indices of assertiveness: the discomfort an individual feels in various situations
which demand assertion, and the probability of response in an assertive fashion. The original
scale is scored in reverse, however, for simplicity: in this paper the higher scores on both indices
indicate more assertiveness.
(6) Extraversion and neuroticism were measured by the E and N scales in the EPQ (Eysenck &
Eysenck, 1975).
(7) Internal locus ofcontrol was measured by Paulhus and Christie’s Control Personality Inventory
(1981).
(8) Cooperativeness was measured by a new scale especially devised for this study. The psycho-
metric procedure of devising this scale requires some detailed description.
The scale construction began by examining the existing measures of psychological constructs
relevant to cooperation, e.g. collectivism. Fifty original items were extracted from various scales
in the literature, or made up to reflect general and specific attitudes towards cooperation and joint
activities (Argyle, 1991). These items were initially classified into the domains Leisure, Leadership,
1022 Luo Lu and MICHAEL ARGYLE
Friends, Family, Education, Clubs, Work, and Committees. Half of the 50 items were in favour
of cooperation, and the other half against.
This item pool was administered to the research sample of 114 adults. Respondents rated
themselves on each item according to a 5-point scale ranging from “Strongly agree” to “Strongly
disagree”. The scale was re-administered 6 months later to the same sample.
Using these data, item-to-scale correlations were computed for all the items. Fourteen items that
had low correlations (P < 0.05) with the total scale were dropped. The final version of the
Cooperativeness Scale is given in the Appendix.
RESULTS
Analyses of cooperativeness
Responses on the final version of the 36-item Cooperativeness Scale were subjected to a factor
analysis with varimax rotation. The factor analysis was performed on Time 1 and Time 2 data
separately. However the factor structures yielded were similar on the two data sets. This cross
validation could be taken as evidence of internal structural reliability of the scale.
The original domains disappeared, and four factors emerged, accounting for 36.7% (Time 1) and
38% (Time 2) of the total variance. They can be labelled as: Factor 1 (11 items): “Managing
conflicts/negotiation”; Factor 2 (12 items): “Decision making”; Factor 3 (6 items): “Joint
activities/doing things together”; Factor 4 (7 items): “Group productivities/working together”.
The internal consistency (alpha) coefficients for the scales administered at Time 1 and Time 2
ranged from 0.55 to 0.77. The test-retest reliability over 6 months was also acceptable (see
Table 1). The 36-items scale at this stage still consisted of roughly half positive and half negative
items.
In all the further analyses, the total score of the 36 items and the four factor scores will be used.
There was some preliminary validity data on the Cooperativeness Scale. Table 2 presents
correlations between scores of cooperativeness and various psychological measurements used in this
study.
Cooperativeness correlated positively with general index of social skills measured by COMQ,
especially in aspects of managing conflicts/negotiation (Factor l), and joint activities/doing things
together (Factor 3). Cooperativeness also correlated positively with self-esteem, especially in
domains of decision making (Factor 2) whereas this aspect of cooperativeness correlated negatively
with neuroticism. It seems that different aspects of cooperativeness are linked with different
psychological qualities and skills. Evidence of convergent validity also came from correlations
between cooperativeness and extraversion, since extraverts are generally regarded as having
superior social skills and enjoying joint activities.
However, the Cooperativeness Scale is not just a general index of positive or desirable traits and
skills. It showed no relationship with internal locus of control (0.08) or assertiveness (0.17 n.s.).
The divergence between cooperativeness and assertiveness is conceptually interesting, since it
reveals that although cooperation undoubtedly requires social skills, assertive skills alone are not
sufficient.
When we examine the predictive validity of the Cooperativeness Scale, we found that coopera-
tiveness correlated positively with happiness, but not with mental health. On the one hand, this
evidence fits nicely with the hypothesized linkage between cooperativeness and well-being; on the
other hand, it reflects the fact that there are a lot of psychiatrically normal people around who
are “loners”.
Finally, the Cooperativeness Scale also revealed a clear sex difference: women tended to be more
cooperative than men. There was an interesting age difference as well. Where cooperation in
decision making is concerned, younger people were more cooperative than their older counterparts.
This might reflect changes in social values over the generations.
In summary, the reliability of the Cooperativeness Scale was acceptable, and the validity was
generally congruent with our conceptualization of the cooperativeness construct, and the existing
literature on relevant topics outlined in the introduction section. Nevertheless, more detailed work
on this new scale needs to be carried out in the future.

Causes of happiness and mental health
Since measurements of happiness and mental health were administered twice, at the beginning
and end of this study, correlations between baseline (Time 1) and latent (Time 2) measures of each
variable were computed first. The Pearson correlation coefficient for happiness over 6 months was
0.65 (P < O.OOl), and that for mental health was 0.75 (P -c 0.001). Furthermore, there was no
difference detected on t tests between either pair of baseline and latent measures. It seems both

levels of happiness and psychological symptoms were very stable over time. Therefore, in all the
further correlation analyses, scores on personality (including cooperativeness) and skills measures
were those taken at Time 1, and happiness and mental health were those taken at Time 2.
Table 3 presents the pattern of correlations between demographic variables, personality factors,
social skills, and happiness and mental health.
First, there was no correlation between sex and either happiness or mental health. However, there
was a negative correlation between age and happiness: younger people tend to be happier in this
sample. Second, the personality measures all correlated with happiness. Self-esteem, extraversion,
internal locus of control, and cooperativeness had positive relations with happiness, while
neuroticism had a negative relation. The directions of correlations were all reversed for (poor)
mental health, though cooperativeness had no relation with symptoms. Third, general social skills
and the response index of assertiveness correlated positively with happiness. However, skills
measurements did not correlate with mental health. Finally, there was a high negative correlation
between happiness and (poor) mental health.
Following these correlation patterns, two sets of multiple regression analyses were performed to
predict happiness and mental health. To predict latent happiness (Time 2) from all its correlates,
a stepwise multiple regression was first performed. Age, concurrent mental health (Time 2),
extraversion, and cooperativeness (Factor 3) all emerged as significant predictors. In order to
explore their independent contributions toward happiness, a hierarchical multiple regression
analysis then followed. Baseline happiness (Time 1) was entered into the regression equation first,
followed by these identified predictors. Even after controlling for the baseline happiness, effects of
age, mental health, extraversion and cooperativeness in regard of joint activities, on happiness were
still significant. Results of the hierarchical regression are presented in the upper half of Table 4.
To predict latent mental health (Time 2) from all its correlates, a stepwise multiple regression
was first performed. Concurrent happiness (Time 2) and neuroticism emerged as significant
predictors. In order to explore their independent contributions toward mental health, a hierarchical
multiple regression analysis then followed. Baseline mental health (Time 1) was entered into the
regression equation first, followed by these identified predictors. After controlling for the baseline

mental health, effects of happiness and neuroticism on mental health were still significant. Results
of the hierarchical regression are presented in the lower half of Table 4.
The results so far suggested that after partialling out the baseline effects, the relationship between
happiness and mental health was bi-directional; and each could be independently predicted by a
set of psychological variables. These relationships are presented graphically in Fig. 1.
To carry further the study on happiness, another method of analysis was adopted. The entire
group was divided into four subgroups, according to the group mean scores on happiness in Times
1 and 2. The Hi-Hi Group consisted of people who were stably happy, i.e. those who scored above
the mean at both Times 1 and 2. The Lo-Lo Group consisted of people who were stably unhappy,
i.e. those scored below the mean at both Times 1 and 2. The Hi-Lo Group was the risk group,
consisting of people who scored above the mean at Time 1 but fell below the mean at Time 2. The
Lo-Hi Group was the prognostic group, consisting of people who scored below the mean at Time 1
but rose above the mean at Time 2. By comparing the Hi-Hi Group with the Hi-Lo Group, we
should be able to identify the risk factors to happiness. Similarly, by comparing the Lo-Lo Group
with the Lo-Hi Group, we should be able to identify the prognostic factors to happiness. Significant
t tests results on these two analyses ,are given in Table 5.
Symptoms of depression, extraversion, and cooperativeness over group productivities/working
together, seemed to distinguish the Hi-Hi Group from the Hi-Lo Group. Therefore, more

might be risky to happiness.
Internal locus of control and cooperativeness over joint activities/doing things together seemed
to distinguish the Lo-Lo Group from the Lo-Hi Group. Therefore, Internal locus of control and
cooperativeness over doing things with other people might enhance one’s happiness.
Causes of cooperativeness

their correlates. Results are
First, extraversion and sex predicted overall cooperativeness. Women were more cooperative
than men in general. Second, social skills predicted aspects of managing conflicts/negotiation in
cooperation. Third, self-esteem and sex predicted cooperation concerning decision making. People
with high self-esteem and women were more willing to cooperate on decision making. Fourth, social
skills and sex predicted cooperation on joint activities. People with better social skills and women
were more willing to cooperate in joint activities. Fifth, extraversion predicted cooperation on
group productivities. These relationships are graphically presented in Fig. 2.
In a study which involved multiple psychological variables, it is necessary to check the
intercorrelations between these variables before we can make sense of the complicated results.
Table 7 gives these intercorrelations. As we can see, these psychological constructs were all closely
correlated, with a few exceptions. Cooperativeness did not correlate with assertiveness or internal
locus of control. The intercorrelations between assertiveness and social skills, self-esteem, extraver-
sion, neuroticism, and internal locus of control might explain the lack of contribution from
assertiveness in results so far presented. Contributions of other psychological variables might have
included those variances originally accounted for by assertiveness.
Sex d@erences
Finally, t tests were performed to compare men and women on personality, skills, happiness and
mental health. Significant results are presented in Table 8.
There was no sex difference on either happiness or mental health. While women tend to be
socially more skilled and more cooperative over joint activities, they also tend to be more neurotic
than men.
DISCUSSION
The theoretical implications of the results related to reliability and validity of the Cooperative-
ness Scale have already received elaborated discussion at the beginning of the Results section. We
first wanted to establish the existence of a cooperativeness dimension. The 36 items did not produce
a general factor, but instead 4 orthogonal ones. However Cronbach’s alpha was 0.77 at Time 1
and 0.81 at Time 2; we therefore used both the total score and the 4 factor scores in the analyses.
The total cooperation measure appears to have some psychological reality: it is significantly higher

Factor I had no correlation with happiness; this factor consists of items about friction in groups,
like “Social clubs have a lot of internal friction and clashes between individuals”. This may reflect
lack of cooperative skills, or perhaps experience of difficult groups. Factor II also had no
correlation with happiness; it consists of items about decision-taking and leadership, such as “It
is usually best if one partner in a relationship is the boss”. Factor III came out most clearly related
to happiness and contained the following items:
“Most forms of leisure are better done in groups.”
“Family members always enjoy doing things together.”
“Decisions taken by groups are better than those taken by individuals.”
“It is more fun doing things with friends than alone.”
“Team members usually pull together, rather than seeking individual glory.”
“Group leisure activities, like choirs, orchestras, theatricals and folk dancing, are often
tiresome and irritating.”
The main hypothesis was that cooperativeness at Time 1 would predict happiness at Time 2. The
multiple regression found that happiness was quite stable over a 6-month interval (r = 0.66), but
the cooperativeness Factor III was also a significant predictor, as was age, extraversion and mental
health.
A second analysis was made of the sub-groups of subjects whose happiness increased or de-
creased over the 6 months. The original highs who became less happy were initially less cooperative
on Factor IV (working together), less extraverted, and more depressed. Those who were initially
low on happiness who became happier were initially more cooperative on Factor III and higher
on internal control. So Factor IV is a risk factor for the happy, while Factor III can help the
unhappy. Factor III items are all about enjoying doing leisure activities-together in groups and
with friends. They are not so much about cooperative skills, but rather about a cooperative attitude.
Factor IV is similar but is about joint activities at work, e.g. “Involvement in joint projects at work
is very satisfying”. As a check, all the four factors were correlated with the P scale which was given
with the E and N scales in the EPQ. However, none of the correlations was significant.
It was hypothesized that lack of cooperativeness would predict poor mental health. The two
mental health measures (MHQ and N) had low negative correlations with cooperation; Factor I
correlated -0.20 (P < 0.05) with N; but cooperation did not predict mental health in the regression
analyses. However mental health and happiness had a two-way relationship, each predicting the
other, as shown in Fig. 1, and depression was a risk factor for happy people as shown above.
What are the causes of cooperativeness? The total score on cooperativeness is predicted only by
extraversion and sex (women more). The separate factors had different predictors: Factor III is
predicted by social skills and sex, Factor IV by extraversion. Factor III is the factor which came
out most strongly linked to happiness. It is about having a positive attitude to engaging in group
leisure activities with friends. This sounds very similar to extraversion, but the correlation with
extraversion was only 0.23 and extraversion did not predict it, so it is evidently something different.
It is partly an attitude, but partly perhaps a skill too, the skill needed to enjoy group activities.
