Response bias influences mental health symptom reporting in patients with obstructive sleep apnea

Annals of Behavioral Medicine (Impact Factor: 4.2). 11/2001; 23(4):313-317. DOI: 10.1207/S15324796ABM2304_11


The Medical Outcomes Study (MOS) inventory is widely used to assess quality of life in chronically ill patients. Although
response bias was addressed during its initial validation, we are unaware of subsequent studies examining how personality
characteristics influence responses on this instrument. We examined the impact of response bias on MOS data reported by 44
obstructive sleep apnea (OSA) outpatients who completed the MOS and Marlowe—Crowne Social Desirability Scale (MC). Social
desirability implies responding in a way that the participant believes will be viewed favorably; MC is often used to statistically
control for this form of response bias on self-report measures. The MOS yielded 2 summary scales (Mental and Physical Health)
and 8 dimensions (based on Short Form-36 [SF-36]). Data were analyzed using multiple regression analyses. Results show that
there is a significant relation between MC and the Mental and Physical Health factors (R2 = .194, F = 5.069, p = .011) and the eight SF-36 dimensions (R2= .359, F =2.448, p = .032). Post hoc analyses did not reveal that any one independent variable was a superior predictor of
the MC. Participants scoring high on the MC reported 31% greater health than participants scoring low on the MC. Findings
suggest that response bias has a significant influence on MOS data from OSA patients, with the greatest impact on mental health
indexes. Controlling for response bias on the MOS and other self-report measures is important in both research and clinical
situations with OSA and potentially other chronically ill patients.

    • "The analysis recognises the possible impact of the social desirability bias, whereby especially representatives of energy ministries might want to present their organisation in a favourable light, thereby distorting the answers (Paulhus 2002). However, also the private sector and utility representatives might deliberately exaggerate their basic agency and communion values such as personal agency and commonalty relating to their role in the advancement of renewable energy technologies (Paulhus 1984, 1991; Bardwell et al. 2001; Sullivan and Scandell 2003). The methodological triangulation allows for a more holistic, complete and contextual understanding of barriers to RE, and provides a connection of different perspectives from different sectors (Banister et al. 1994; Denzin 1978; Flick 1995, 2011; Holtzhausen 2001; Jakob 2001).

    • "In addition, collecting data at the mobilization site does not provide an optimal, non-stressful baseline. Social desirability, or the tendency to present oneself in an especially favorable way, was a significant predictor of mental function, as has been reported previously [52]. This suggests that like non-veterans, some military personnel present themselves as having better mental function than may in fact be true due to their biased reporting style. "

    ABSTRACT: Background Physical and mental function are strong indicators of disability and mortality. OEF/OIF Veterans returning from deployment have been found to have poorer function than soldiers who have not deployed; however the reasons for this are unknown. Methods A prospective cohort of 790 soldiers was assessed both pre- and immediately after deployment to determine predictors of physical and mental function after war. Results On average, OEF/OIF Veterans showed significant declines in both physical (t=6.65, p<.0001) and mental function (t=7.11, p<.0001). After controlling for pre-deployment function, poorer physical function after deployment was associated with older age, more physical symptoms, blunted systolic blood pressure reactivity and being injured. After controlling for pre-deployment function, poorer mental function after deployment was associated with younger age, lower social desirability, lower social support, greater physical symptoms and greater PTSD symptoms. Conclusions Combat deployment was associated with an immediate decline in both mental and physical function. The relationship of combat deployment to function is complex and influenced by demographic, psychosocial, physiological and experiential factors. Social support and physical symptoms emerged as potentially modifiable factors.

    • "UC patients with high levels of conventionality/social desirability reported better physical function. Social desirability has been linked to reports of better health, which may explain this association [65]. "

    ABSTRACT: Objective. To assess the role of personality as a predictor of Short form-36 (SF-36) in distressed patients (perceived stress questionnaire, PSQ) with ulcerative colitis (UC) and Crohn's disease (CD). Material and methods. Fifty-four patients with CD and 55 with UC (age 18–60 years) who had relapsed in the previous 18 months, i.e. with an activity index (AI) for UC or CD≥4, PSQ≥60, and without severe mental or other major medical conditions, completed the Buss-Perry Aggression Questionnaire (BPA), the Neuroticism and Lie scales of the Eysenck Personality Questionnaire (EPQ-N and -L), the Multidimensional Health Locus of Control Scale (LOC) (Internal (I), Powerful Other (PO), Chance (C)), the Toronto Alexithymia Scale (TAS) and the SF-36. Results. Multiple linear regression analyses controlling for gender, age and clinical disease activity (AI) in separate analyses for UC and CD showed that the mental and vitality subscales were predicted by neuroticism in both UC and CD. The highest explained variance was 43.8% on the “mental” subscale in UC. The social function subscale was related to alexithymia only in UC, while the role limitation and pain subscales were related to personality in CD only. The physical function subscale related differently to personality in UC and CD. Conclusions. While mental and vitality subscales were predicted by neuroticism in both UC and CD, other subscales had different relationships to personality, suggesting different psychobiological interactions in UC and CD.
