Background: Depression is a chronic condition that affects up to 15% of older adults. The healthogenic effects of regular exercise are well established, but it is still unclear which exercise-related variables characterise the antidepressant effects of exercise. Thus, the purpose of this study was to examine the extent to which exercise-related variables (exercise behaviour, exercise-induced mood, exercise self-efficacy, and social support) can predict depressive symptoms in a cohort of community-dwelling older adults. Methods: This study employed a cross-sectional analysis of questionnaire data from a sample of 586 community-dwelling older Australians aged 65 to 96 years old. Participants completed the Center for Epidemiologic Studies Depression Scale, modified CHAMPS Physical Activity Questionnaire for Older Adults, Four-Dimension Mood Scale, Self-Efficacy for Exercise Scale, and Social Provisions Scale - Short Form. Bivariate correlations were performed, and hierarchical multiple regression was subsequently used to test the regression model. Results: Exercise behaviour, exercise-induced mood, exercise self-efficacy, and social support were all negatively associated with depressive symptoms (r = -0.20 to -0.56). When the variables were entered as predictors into the hierarchical multiple regression model, social support was the strongest predictor of depressive symptoms (beta = -0.42), followed by exercise-induced mood (beta = -0.23), and exercise self-efficacy (beta = -0.07). Exercise behaviour did not explain any additional variance in depressive symptoms. A modest interaction effect was also observed between exercise-induced mood and social support. Conclusion: These findings indicate that social support is the strongest predictor of depressive symptomology in community-dwelling older adults, particularly when combined with positive exercise-induced mood states. When addressing the needs of older adults at risk of depression, healthcare professionals should consider the implementation of exercise programmes that are likely to benefit older adults by improving mood, enhancing self-efficacy, and building social support.

A common form of treatment for Australian men with prostate cancer is a radical prostatectomy (RP). Although sociodemographic and medical factors have been found to be predictive of psychological distress following RP, the traditional masculine norms of self-reliance and stoicism are also implicated in poor psychological outcomes. The strength of the relationship between these masculine norms and distress may vary according to place of residence-specifically, living in regional/remote versus urban areas. The aim of the current study was to investigate these masculine norms as predictors of psychological distress among a sample of men who had received the same treatment for prostate cancer, in the context of place of residence. Participants were 447 men, aged between 42 and 77 years (M = 63.1, SD = 6.4), all of whom had undergone a RP within the previous 6 months. Participants completed self-report measures of psychological distress, physical functioning, self-reliance, and stoicism. As hypothesized, self-reliance and stoicism were independent and unique predictors of psychological distress, after controlling for sociodemographic and medical factors. Place of residence moderated the relationship between stoicism and distress, whereby the relationship was only significant for urban men. The relationship between self-reliance and distress was significant for all men regardless of place of residence. The current study takes an important step toward identifying potentially modifiable and context-specific factors that can impact the experience of psychological distress among men following RP.

Study Objectives: To investigate whether cognitive behavior therapy was effective for older adults with comorbid insomnia and depression in a community mental health setting, and explore whether an advanced form of cognitive behavior therapy for insomnia produced better outcomes compared to a standard form of cognitive behavior therapy for insomnia. Methods: An 8-week randomized controlled clinical trial was conducted within community mental health services, Victoria, Australia. Seventy-two older adults (56% female, M age 75 ± 7 years) with diagnosed comorbid insomnia and depression participated. Three conditions were tested using a group therapy format: cognitive behavior therapy for insomnia (CBT-I, standard), cognitive behavior therapy for insomnia plus positive mood strategies (CBT-I+, advanced), psychoeducation control group (PCG, control). The primary outcomes were insomnia severity (Insomnia Severity Index) and depression severity (Geriatric Depression Scale). Primary and secondary measures were collected at pre (week 0), post (week 8), and follow-up (week 20). Results: CBT-I and CBT-I+ both generated significantly greater reductions in insomnia and depression severity compared to PCG from pre to post (p < .001), which were maintained at follow-up. Although the differences between outcomes of the two treatment conditions were not statistically significant, the study was not sufficiently powered to detect either superiority of one treatment or equivalence of the two treatment conditions. Conclusion: CBT-I and CBT-I+ were both effective at reducing insomnia and depression severity for older adults. Mental health services that deliver treatment for comorbid insomnia with cognitive behavior therapy may improve recovery outcomes for older adults with depression.

Description:
Objectives: Depression is a significant mental health issue among older Australian adults. Research has indicated that insomnia is a key risk factor for the development of depressive symptoms in older adults, and that dispositional hope may be protective against the development of depressive symptoms in this population. This study examined whether dispositional hope and its dimensions, agency and pathways, moderated the relationship between insomnia symptoms and depressive symptoms among older Australian adults. Method: A community sample of 88 men (Mage = 71.11, SDage = 5.54) and 111 women (Mage = 70.25, SDage = 4.64), aged 65–94 years, completed the Insomnia Severity Index, Adult Dispositional Hope Scale, and Centre of Epidemiologic Studies Depression Scale. Results: After controlling for gender, age, relationship status, education level, method of participation, and perceived physical health, results supported the moderation models. The insomnia–depressive symptoms relation was significant for older adults with low and average (but not high) levels of dispositional hope, agency, and pathways. The Johnson–Neyman analyses indicated that the insomnia–depressive symptoms relation was significant for older adults who scored below 27.10 on dispositional hope, below 13.73 on agency, and below 13.49 and above 15.64 on pathways. Conclusion: The results of this study imply that interventions aimed at increasing dispositional hope, agency, and pathways among older adults who experience symptoms of insomnia may reduce their depressive symptoms. A cautionary note, however, is that very high scores on pathways among older adults who experience insomnia symptoms may be detrimental to their mental health.

Previous studies have demonstrated that fatigue is a risk factor for depressive symptoms in mothers of young children. The aim of the present study was to investigate whether the five facets of mindfulness moderated the relationship between fatigue and depressive symptoms in mothers of young children. A sample of 723 mothers of children aged 1–5 years completed the Fatigue Assessment Scale, the Centre for Epidemiologic Studies Depression Scale, and the Five Facet Mindfulness Questionnaire-Short Form. Results showed that four out of the five mindfulness facets (non-judging of inner experience, non-reactivity to inner experience, acting with awareness, and describing) weakened the relationship between fatigue and depressive symptoms. Interaction effects were found to be small. Further investigation of the unique roles of the five mindfulness facets as well as other possible protective factors and interventions that may weaken the fatigue-depressive symptom relationship in mothers of young children is warranted.

The present study examined measurement invariance of the Center for Epidemiologic Studies Depression Scale (CES-D) in community groups of Australian heterosexual men (N = 1106), heterosexual women (N = 2111), gay men (N = 527), and lesbians (N = 712). Confirmatory factor analysis of CES-D item scores supported the theorized oblique 4-factor model. There was support for full measurement invariance across the 4 groups, based on differences in approximate fit indices. In contrast there was support for only partial invariance when the chi-square difference test was applied. Lack of invariance was mostly for depressed affect and somatic symptom items, with noninvariant somatic symptom items showing consistently high factor loadings and thresholds among lesbians compared with the other groups. The findings are discussed in relation to the use of the CES-D, the relevance of different depression symptoms to how depressions is experienced by the different gender and sexual orientation groups, and gender role socialization and minority sexual orientation theories.

Improving the understanding of psychological factors contributing to horse-related accident and injury : Context, loss of focus, cognitive errors and rigidity
Description:
While the role of the horse in riding hazards is well recognised, little attention has been paid to the role of specific theoretical psychological processes of humans in contributing to and mitigating risk. The injury, mortality or compensation claim rates for participants in the horse-racing industry, veterinary medicine and equestrian disciplines provide compelling evidence for improving risk mitigation models. There is a paucity of theoretical principles regarding the risk of injury and mortality associated with human-horse interactions. In this paper we introduce and apply the four psychological principles of context, loss of focus, global cognitive style and the application of self as the frame of reference as a potential approach for assessing and managing human-horse risks. When these principles produce errors that are combined with a rigid self-referenced point, it becomes clear how rapidly risk emerges and how other people and animals may repeatedly become at risk over time. Here, with a focus on the thoroughbred racing industry, veterinary practice and equestrian disciplines, we review the merits of contextually applied strategies, an evolving reappraisal of risk, flexibility, and focused specifics of situations that may serve to modify human behaviour and mitigate risk.

Problem gambling rates in older adults have risen dramatically in recent years and require further investigation. Limited available research has suggested that social needs may motivate gambling and hence problem gambling in older adults. Un-partnered older adults may be at greater risk of problem gambling than those with a partner. The current study explored whether loneliness mediated the marital status-problem gambling relationship, and whether gender moderated the mediation model. It was hypothesised that the relationship between being un-partnered and higher levels of loneliness would be stronger for older men than older women. A community sample of Australian men (n = 92) and women (n = 91) gamblers aged from 60 to 90 years (M = 69.75, SD = 7.28) completed the UCLA Loneliness Scale and the Problem Gambling Severity Index. The results supported the moderated mediation model, with loneliness mediating the relationship between marital status and problem gambling for older men but not for older women. It appears that felt loneliness is an important predictor of problem gambling in older adults, and that meeting the social and emotional needs of un-partnered men is important.
Description:
Background: Living alone is a risk factor for depressive symptoms among older adults, although it is unclear if it is a risk factor for older gay men. A sense of belonging to the gay community is protective and might compensate for living alone. This research investigated whether a sense of belonging with gay friends weakened the relationship between living alone and depressive symptoms among older gay men. Methods: A community sample of 160 Australian gay men aged 65-92 years completed the Center for Epidemiologic Studies Depression Scale and two visual analogue scales assessing a sense of belonging with gay friends. Results: Results supported the moderation model, with increasing levels of belonging with gay friends weakening the relationship between living alone and depressive symptoms. Conclusion: Results imply that enhancing a sense of belonging with gay friends among older gay men who live alone is likely to be a protective factor in relation to depressive symptoms.
Cognitive behaviour therapy for older adults experiencing insomnia and depression in a community mental health setting: Study protocol for a randomised controlled trial
Description:
The Dispositional Hope Scale (DHS; Snyder et al., 1991) is composed of items assessing an individual's perception of his or her agency and pathways. This study examined support for the bifactor structure and relation of the factors in this model with depressive symptoms. It also examined cross-gender measurement invariance for the bifactor model. A community sample of 413 women and 257 men completed the DHS. Confirmatory factor analysis indicated more support for the bifactor model than the 1- and 2-factor models. Results also indicated full measurement invariance across gender for the bifactor and the 2-factor models. The general and the specific agency factors, but not the specific pathways factor, correlated with depressive symptoms. The better support for the bifactor model suggests that ideally hope has to be measured and examined by factors reflecting high covariance for agency and pathways, and also factors reflecting unique variances for agency and pathways. The support for full cross-gender measurement invariance indicated that there are no differences in measurement and scaling properties for the DHS across ratings provided by women and men, and therefore the DHS ratings can be scored in the same way for women and men.

Internalized homophobia is a risk factor for depression among gay men and lesbians. The aim of the study was to test whether the internalized homophobia-depression relation was moderated by gender (stronger among gay men compared with lesbians), age (stronger among younger compared with older gay men and lesbians), and place of residence (stronger among gay men and lesbians who live in rural areas compared with those who live in urban areas). An Australian sample of 311 self-identified gay men and 570 self-identified lesbians, aged 18 to 70 years, completed the Internalized Homophobia Scale and the Centre for Epidemiological Studies Depression Scale. Results indicated that age and gender did not moderate the internalized homophobia-depressive symptoms relation. Place of residence was a significant moderator for gay men but not lesbians. In contrast to the hypothesis, the internalized homophobia-depression relation was significant only among gay men who resided in urban areas. Those who work with gay men should be particularly aware of the significant relationship between internalized homophobia and depressive symptoms among gay men who reside in urban areas.

Description:
There is evidence to suggest that body image dissatisfaction and depressive symptoms are related among lesbians and that the strength of this relationship may be influenced by individuals' sense of belonging to the lesbian community at each of the three layers: broad, organizational, and friendship. The broad layer provides an overarching ideology and, within this layer, individuals may not have direct contact with each other. The organizational layer is represented by groups, organizations, or activities, which exist to bring together lesbians who have a shared interest or proximity, such as lesbian support, social, or interest groups. The friendship layer refers to one's personal network of friends, and it provides general support and acceptance of oneself as a whole person. A sample of 162 self-identified Australian lesbians completed measures of body image satisfaction, depressive symptoms, and sense of belonging. Results demonstrated that sense of belonging to each layer moderated the body image dissatisfactiondepressive symptoms relationship such that the relationship weakens with increasingly higher levels of sense of belonging. Results further showed that high levels of sense of belonging to the organizational and friendship layers were particularly protective. Examining each layer of community simultaneously has shown the importance of more intimate relationships, in addition to the relationships at the broad layer. The results have significant implications for treatment interventions. Practitioners should consider ways to connect lesbians to these more intimate layers of community.
Description:
Sense of belonging to the general and broader gay communities has been shown to be beneficial for gay men’s mental health. This research investigated the interrelations between sense of belonging to three forms of gay community (the broader gay community, gay groups, and gay friends), sense of belonging to the general community, and depressive symptoms by examining a path model. A community sample of 177 gay men, aged 18 to 79 years, completed the Sense of Belonging Instrument–Psychological subscale, the Centre for Epidemiological Studies–Depression Scale, and the Sense of Belonging within Gay Communities Scale. The model provided excellent fit to the data in which sense of belonging to the general community mediated the relationships between a sense of belonging to gay groups and with gay friends and depressive symptoms. Results imply that enhancing gay men’s sense of belonging to gay groups and with gay friends is likely to be associated with fewer depressive symptoms, by virtue of their enhanced sense of belonging to the general community.
Description:
The current study examined the measurement and structural invariance of the Center for Epidemiological Studies Depression Scale (CES-D; Radloff, 1977) across ratings provided by older adult men (. n=. 573) and women (. n=. 605). Ratings were modeled in terms of the original four-factor oblique model: a simple structure with correlated factors for Depressed Affect, Positive Affect, Somatic Symptoms, and Interpersonal Difficulties. Multiple-group confirmatory factor analysis supported full measurement and structural invariance, and no sex difference for the four latent factors. These findings indicate good support for measurement and structural invariance of CES-D ratings across older adult men and women. The psychometric and practical implications of the findings are discussed.
