  ABSTRACT: Drinking motives have been established as an important construct in the prediction of alcohol use and drinking problems among younger adults, but there is little understanding about the drinking motivations of older adults. Although emerging evidence shows the importance of studying older adults' own reasoning for their alcohol consumption, measures that have been used to assess such reasons lack psychometric assessment. This study aims to validate the three-dimensional structure of the Drinking Motives Questionnaire (DMQ) in older adults and to investigate the relationships between drinking motives and alcohol use. A sample of community dwelling older adults (N=370) completed self-report measures assessing drinking behavior and motives for drinking. Using confirmatory factor analysis, the results supported a three-factor model of drinking motives. Multi-group analysis of invariance showed support for configural and metric invariance, and partial support was met for scalar invariance. Social motivations for drinking were the most frequently endorsed, followed by enhancement, and coping motives. Males reported more frequent drinking for each of the three motives. Social motives were consistently related to drinking behaviors and coping had a direct relationship to drinking problems. Overall, the study shows that the DMQ has promise as a measure for use with older adults.

  ABSTRACT: Attitudes are known to exert a powerful influence on a range of behaviors. The objective of this study was to investigate the contribution of attitudes toward one's own aging to satisfaction with life and physical and mental health measured in a sample of community-dwelling older adults. Adults who were part of a larger study of health and well-being in rural and regional Australia aged ≥60 years (N = 421) completed a cross-sectional postal survey comprising the Attitudes to Aging Questionnaire, the 12-Item Short Form Health Survey (SF-12), the Satisfaction with Life Scale, the Geriatric Anxiety Inventory, and the Center for Epidemiological Studies Depression Scale. Overall, attitudes to aging were positive in this sample. More positive attitudes to aging were associated with higher levels of satisfaction with life, better self-report physical and mental health on the SF-12, and lower levels of anxiety and depression, after controlling for confounding variables. Better financial status and being employed were both associated with more positive attitudes to aging and better self-reported physical health. Relationship status was also significantly associated with mental health and satisfaction with life, but not physical health. The promotion of successful aging is increasingly becoming important in aging societies. Having positive attitudes to aging may contribute to healthier mental and physical outcomes in older adults. Overcoming negative stereotypes of aging through change at the societal and individual level may help to promote more successful aging.

  Article: Attentional processes and responding to affective faces in youth with borderline personality features.

  ABSTRACT: This study examined attentional biases for emotional faces in borderline personality disorder (BPD). Twenty-one outpatient youth (aged 15-24 years) meeting three or more DSM-IV BPD criteria and 20 community-derived participants (aged 15-24 years) with no history of psychiatric problems and not meeting any BPD criteria completed a modified dot-probe task that tested automatic (30ms) and controlled (500ms) stages of information processing. The findings indicate that, compared with healthy controls, youth with borderline features were faster to respond to congruent rather than incongruent fear stimuli. This effect was independent of state anxiety and was observed during the 30ms presentation of fearful faces. There was no significant effect for happy or angry faces. Youth with borderline features were also slower to respond to incongruent rather than paired neutral trials, indicating difficulties in disengaging attention from the perceived threat. Such differences were not found for the healthy controls. Thus, youth with borderline features had an attentional bias for fearful faces that reflected difficulty in disengaging attention from threatening information during pre-conscious stages of attention. This finding extends previous research highlighting the diminished capacity for affect regulation and subsequent engagement in behavioural strategies to avoid distress in BPD. Future research should explore the relationship between information processing, emotion regulation in adult BPD samples.

  Article: Testing the Stroop Effect in a Nonclinical Sample: Hypervigilance or Difficulty to Disengage?

  Natalie Peach, Martina Jovev, Alexander Foster, Henry Jackson
  [show abstract] [hide abstract]
  ABSTRACT: Traditional interpretations of the bias have suggested that anxious people are hypervigilant to threat; that is, their attention orients more quickly towards threatening stimuli. Recent research has questioned the validity of this interpretation, suggesting that difficulty disengaging attention from threat might play a role in the attentional bias. A limited number of experimental paradigms have differentiated between hypervigilance and difficulty disengaging. In this study, 169 undergraduate students completed an emotional Stroop task to investigate the presence of an attentional bias to threat, and a lexical decision task to differentiate between hypervigilance and difficulty disengaging. Hypotheses regarding the emotional Stroop task were partially supported; Stroop effects were found in some, but not all, of the threat-types investigated. Lexical decision task results lent support for the hypervigilance hypothesis. Anxiety levels did not predict the extent of the attentional bias. Results are discussed in relation to future directions for attentional bias research.

• Article: A Model of Obsessive‐Compulsive Phenomena in a Nonclinical Sample

  Darryl Wade, Michael Kyrios, Henry Jackson
  [show abstract] [hide abstract]
  ABSTRACT: On the basis of the relevant theoretical and empirical literature, the present study investigated the merits of a psychological vulnerability model of obsessive-compulsive activity in a nonclinical sample (n = 200). The model proposed that certain personality traits, possibly mediated by negative mood, would be associated with the experience of obsessive-compulsive phenomena. Structural equation modelling indicated that obsessive-compulsive phenomena were, in part, predicted by the varying predisposing personality features of neuroticism, perfectionism, and low subscription to a set of moral principles, with negative mood an important mediator in these interrelationships. The results are discussed in the light of past findings.
