ABSTRACT

Optimism involves the general expectation good things will occur and greater optimism is associated with a number of positive life outcomes related to better mental and physical health. These outcomes include reduced likelihood of depression, more effective immune functioning and lower mortality. Emotional intelligence, which consists of adaptive emotional functioning, may be a foundation for optimism. This meta-analysis examined the relationship between emotional intelligence and optimism across 6889 participants from 25 independent samples. Across studies, a higher level of emotional intelligence was associated with greater optimism with a weighted effect size of, r = .35, p < .001. Measurement approach and country of participants moderated the effect size. These results have relevance for the design of positive psychology interventions.

ABSTRACT

BACKGROUND: The purpose of this study was to develop and to validate a measure of cultural responsiveness that would assist mental health practitioners across a range of disciplines, in Australia, to work with Indigenous clients. AIM: The Cultural Responsiveness Assessment Measure (CRAM) was developed to provide a tool for practitioners and students to evaluate their own culturally responsive practice and professional development. METHOD: Following expert review for face validity the psychometric properties of the measure were assessed quantitatively, from the responses of 400 mental health practitioners. RESULTS: Confirmatory Factor Analysis yielded a nine factor, 36 item instrument that demonstrated strong convergent and discriminant validity as well as test-retest reliability. CONCLUSIONS: It is anticipated that the CRAM will have utility as both a learning tool and an assessment measure, for mental health practitioners to ensure that services are culturally responsive for Aboriginal and Torres Strait Islander people.

ABSTRACT

Purpose in life consists of having a sense of meaning and purpose regarding one's activities as well as an overall sense that life is meaningful. This study reports a comprehensive assessment of the relationship of purpose in life with depression and anxiety. A meta-analysis (total n = 66,468, total k = 99) investigated the association of purpose in life with depression and anxiety. Across samples, greater purpose in life was significantly associated with lower levels of depression and anxiety. The mean weighted effect size between purpose in life and depression was r = -0.49, [95% confidence intervals, CIs: -0.52, -0.45], p < 0.001. For the purpose in life and anxiety the mean weighted effect size was r = -0.36, [95% CIs: -0.40, -0.32], p < 0.001. The association of purpose in life with mental health was stronger for clinical populations, especially with regard to the relationship with anxiety. Both approach deficits and avoidance motivation are argued to play a role in the relationship between purpose and psychopathology, with greater purpose potentially limiting avoidance tendencies and reducing the effects of depression and anxiety. Understanding the role that purpose in life may play in depression and anxiety could help to inform current conceptualizations of these disorders and improve treatment outcomes.

ABSTRACT

The objective of this study was to assess the psychometric characteristics of the Arabic version of the Assessing Emotions Scale (AES-Ar) among a sample of Lebanese young adults. A total of 402 Lebanese university students and their contacts were recruited for the study. A confirmatory factor analysis (CFA) investigated the structure of the scale. The CFA for investigating a four-factor solution using all items showed the fit indices were acceptable (χ2 /df = 1803.15/489 = 3.69; RMSEA = 0.082 [0.078-0.086]; CFI = 0.88; TLI = 0.87) but the loading of the negatively worded items 5, 28 and 33 were low on their respective factors. When testing the four-factor model after removing items 5, 28 and 33, the results improved further with good fit indices of the model (χ2 /df = 1383.184/399 = 3.46, RMSEA = 0.078 [0.074-0.0832], CFI = 0.91 and TLI = 0.90) and good factor loading of each item on each factor, respectively. No measurement invariance was found between genders. The AES-Ar Cronbach's α was excellent (0.976). Higher Assessing Emotions Scale-Ar scores, based on the 30 positively worded items, were significantly associated with greater self-esteem (r = .547; p < .001), and less depression (r = -.295; p < .001). Our results suggest that the AES-Ar is appropriate for use to measure emotional intelligence in Arabic-speaking populations.

ABSTRACT

BACKGROUND: Recovery concepts were conceived by, and for, people living with mental health issues. Practitioners are key in translating recovery principles into action. Therefore, practitioners' perceptions should be routinely assessed to facilitate in-service training, professional development, and curriculum redesign. AIM: To explore practitioners' and trainees' current perspectives regarding the concept of recovery. METHODS: The study used a qualitative exploratory design with in-depth interviews to explore ten fully trained practitioners and eight trainees' perspectives on recovery. RESULTS: The findings revealed a shared understanding of recovery among practitioners and trainees. Many responses explained recovery as a process involving internal and external conditions, however, some revealed medically oriented perspectives and/or were unclear about recovery terminologies. CONCLUSIONS: There is convergence and growing acceptance of the recovery practice principles among practitioners and trainees. However, the results suggest that the recovery principles/terminologies have not yet been universally adopted. IMPLICATIONS FOR PRACTICE AND RESEARCH: Continuous training on recovery principles is needed, incorporating emerging terminologies and principles. Also, education providers are encouraged to continue to review their training to incorporate emerging issues and trends in recovery-oriented practice. Finally, research is needed to enhance the development and delivery of recovery-focused practice.

ABSTRACT

OBJECTIVE: Despite innovations in contraceptive methods, unintended pregnancies remain common. Researchers have examined psychological approaches to decrease unintended pregnancies through contraceptive use. These interventions have involved applying aspects of social cognitive theory, the health belief model and self-determination theory. Research findings on the effects of these psychological approaches show conflicting evidence. The aim of this meta-analysis was to clarify the impact of these psychological interventions on unintended pregnancies DESIGN: Meta-analysis of randomized controlled trials (RCTs) of psychological interventions intended to prevent unwanted pregnancies through an increase in the use of contraceptive methods METHODS: A systematic search of databases and article reference lists led to 26 relevant RCTs with a total of 31,222 participants RESULTS: The odds ratio for pregnancy in the psychological intervention condition = .83, 95% CI [.75, .93]. The results also showed that the longer an intervention's follow-up period was, the less the prevention effect. Quality assessment of included studies indicated that all used a treatment manual and reported attrition. It also showed that most studies reported the reasons for drop-out and assessed the facilitators' adherence to the intervention protocol. The proportion of variability due to chance amongst studies was I2  = 22%. Duval and Tweedie's Trim and Fill showed a difference between the observed and the adjusted values. The adjusted value, representing a conservative estimate of effect size, was OR = .891, 95% CI [.777, .999] CONCLUSIONS: Altogether, these results support the efficacy of psychological interventions aimed at preventing unintended pregnancy through contraception.

ABSTRACT

INTRODUCTION: Parental conditional regard involves parents giving or withdrawing affection and approval, depending on children's and adolescents' compliance with parental expectations, to shape behaviors and traits. Research grounded in self-determination theory suggests parental conditional regard harms psychological development. Using self-determination theory as a theoretical foundation for investigating outcomes associated with parental conditional regard, the present study consolidated meta-analytic associations between parental conditional regard and four theoretically important individual difference correlates: introjected self-regulation, contingent self-esteem, depressive symptoms, and relatedness. METHODS: Following PRISMA guidelines, a systematic literature search was conducted using the PsycINFO, ProQuest, and EBSCO databases for English-language, peer-reviewed published studies and unpublished studies. Eligible studies reported an association between parental conditional regard and the four theoretically derived correlates or another correlate of interest in pre-adolescent children, adolescents, or young adults. The results were based on a random-effects model for meta-analyses and the Q statistic for moderator analyses. RESULTS: Across 31 samples in total, greater parental conditional regard was significantly associated with more introjected regulation (r = .33), contingent self-esteem (r = .29), and level of depressive symptoms (r = .22); and less relatedness (r = -.24). Moderator results for parental conditional regard type found parental conditional regard's association with introjected regulation was significantly stronger for studies measuring giving regard (parental conditional positive regard) than withdrawing regard (parental conditional negative regard). The association of parental conditional regard with depressive symptoms was significantly stronger for studies measuring parental conditional negative regard than parental conditional positive regard. CONCLUSIONS: The meta-analytic results provide theoretical and empirical support for the connections between self-determination and the impact of parental conditional regard.

ABSTRACT

BACKGROUND: Selective mutism is a rare childhood anxiety disorder characterized by a consistent failure to speak in certain social situations where speech is expected, despite fluent speech in other situations. The purpose of this meta-analysis was to investigate the efficacy of psychological interventions for selective mutism in randomized controlled trials (RCTs). METHODS: Five RCTs with a total of 233 participants were analysed using a random-effects model. A quality assessment of the included studies revealed that psychometrically sound measures and treatment manuals were used across all studies. RESULTS: The results of the analyses showed psychological interventions to be more effective than no treatment, with the overall weighted effect size of g = 0.87, indicating a large mean treatment effect. This effect did not significantly differ with whether only selective mutism specific or nonselective mutism specific measures were included in the analysis. CONCLUSIONS: These findings provide support for the efficacy of psychological treatment for selective mutism. Future research could examine the effects of the successful treatments identified in this meta-analysis when compared with a psychological placebo or another bona fide treatment.

ABSTRACT

This meta-analysis evaluated the association between trait perspective taking and romantic relationship satisfaction. The study synthesized the association in 20 separate samples in a total of 18 published and unpublished studies, involving a total of 4,678 participants. The studies were completed by many different research teams, using different samples, different measures, and various correlational research designs. The results showed a significant association between trait perspective taking and romantic relationship satisfaction (r = .21, 95% confidence intervals [.17, .25]). The results did not vary significantly with whether the respondents were men or women, whether they rated their own perspective taking or that of their partner, or whether the perspective taking assessed was general or specific to the partner. The findings provide a basis for future intervention studies that test whether increasing perspective taking has a positive effect on relationship satisfaction.

ABSTRACT

OBJECTIVE: The current research evaluated whether Go/No-go training for highly palatable (HP) food affected attention bias for HP food (an automatic/implicit outcome) and intention to eat unhealthy food (a controlled/explicit outcome). METHOD: A sample of Australian adults representative for age, gender and Body Mass Index (BMI) (N = 561, Mage = 46.31 years, SD = 16.75, 52.3% women, MBMI = 27.11, SD = 6.34) completed self-report measures of dietary psychological constructs and food image modified Stroop tasks as measures of pre- and post-test attention bias for HP food. After random assignment of participants to two conditions, a Go/No-go intervention was used to train HP food targeted inhibitory control in the experimental group, or general inhibitory control in the control group. All research tasks were delivered online. RESULTS: The experimental, HP food inhibitory control training group reported intention to eat less unhealthy food than the control group, F (1, 637) = 4.81, R2 = 0.09, p = .029. Counter to expectations, the experimental group exhibited a heightened attention bias to HP food images after the training, F (1, 637) = 9.48, R2 = 0.39, p = .002. CONCLUSION: Go/No-go training for food may improve both top-down and bottom-up inhibitory control, using both automatic and controlled processes. Further, it may not be effective in lowering attention bias for HP food, but may be effective in lowering unhealthy food intake despite raising attention bias for HP food. Further research that tests these effects using varied reaction time tasks is needed to confirm these results and to explore possible alternative explanations.

ABSTRACT

Objective: Telomeres are the caps at the end of chromosomes. Short telomeres are a biomarker for worsening health and early death.Design: The present study consolidated research on meditation and telomere length through a meta-analysis of results of studies examining the effect of meditation on telomere length by comparing the telomere length of meditating participants with participants in control conditions.Results: A search of the literature identified 11 studies reporting 12 comparisons of meditating individuals with individuals in control conditions. An overall significant weighted effect size of g =.40 indicated that the individuals in meditation conditions had longer telomeres. When an outlier effect size was trimmed from the analysis, the effect size was smaller, g =.16. Across studies, a greater number of hours of meditation among participants in meditation conditions was associated with larger effect sizes.Conclusion: These findings provide tentative support for the hypothesis that participants in meditation conditions have longer telomeres than participants in comparison conditions, and that a greater number of hours of meditation is associated with a greater impact on telomere biology. The results of the meta-analysis have potential clinical significance in that they suggest that meditation-based interventions may prevent telomere attrition or increase telomere length.

ABSTRACT

This study examined whether the status (central or peripheral position) of individuals in a friendship network and the quality of a friendship network represent key mechanisms in determining how emotional intelligence is associated with subjective well-being. Using data collected from 217 Chinese senior undergraduates, we found that the interaction of the quality of a friendship network and a peripheral position in a friendship network mediated relations of emotional intelligence with subjective well-being. Although a central position in a friendship network did not interact with the quality of a friendship network, it did mediate the relations of emotional intelligence with subjective well-being on its own. The findings expand the growing body of research findings on the association between emotional intelligence and subjective well-being by investigating the role of friendship networks and highlight the importance of a network perspective in understanding the association.

ABSTRACT

OBJECTIVE: The current research created and validated three new measures of psychological mechanisms associated with dietary behavior: (i) a Dietary Goal-Desire Incongruence scale assessed the degree of conflict between ideal dietary behavior and incongruent tempting desires; (ii) a Motivation for Dietary Self-control scale measured the extent and type of motivation, according to Self-Determination Theory, which may be experienced when trying to control dietary behavior; and (iii) a Satisfaction with Dietary Behavior scale measured successful dietary goal-behavior alignment. METHOD: A representative sample of Australian adults (N = 448, Mage = 45.7 years, SD = 16.98, 50.2% women) rated items assessing the three target constructs and also completed established scales that measure related and unrelated constructs. RESULTS: Exploratory factor analyses indicated a 1-factor Dietary Goal-Desire Incongruence scale (6 items), 3-factor Motivation for Dietary Self-control scale (11 items), and a 1-factor Satisfaction with Dietary Behavior scale (8 items). Confirmatory factor analyses also supported the model fit of each scale's factor solution. Internal consistency as assessed by Cronbach's alpha (α) was 0.94, 0.78, and 0.94 for the three scales, respectively. A follow-up mediation analysis revealed a stage model of psychological factors related to dietary behavior (as assessed by these three scales) that build on each other. Test-retest reliability was high for each scale (r = .71-.84) and showed sound predictive validity. CONCLUSION: The Dietary Goal-Desire Incongruence scale, Motivation for Dietary Self-control scale, and Satisfaction with Dietary Behavior scale show good psychometric properties and are brief, easy to administer measures. The utility of the scales can be explored further with other populations and in intervention studies.

ABSTRACT

Two studies, with a total of 707 participants, developed and examined the reliability and validity of a measure for anticipatory traumatic reaction (ATR), a novel construct describing a form of distress that may occur in response to threat-related media reports and discussions. Exploratory and confirmatory factor analysis resulted in a scale comprising three subscales: feelings related to future threat; preparatory thoughts and actions; and disruption to daily activities. Internal consistency was .93 for the overall ATR scale. The ATR scale demonstrated convergent validity through associations with negative affect, depression, anxiety, stress, neuroticism, and repetitive negative thinking. The scale showed discriminant validity in relationships to Big Five characteristics. The ATR scale had some overlap with a measure of posttraumatic stress disorder, but also showed substantial separate variance. This research provides preliminary evidence for the novel construct of ATR as well as a measure of the construct. The ATR scale will allow researchers to further investigate anticipatory traumatic reaction in the fields of trauma, clinical practice, and social psychology.

ABSTRACT

BACKGROUND AND AIMS: A number of studies have investigated connections between probability discounting and gambling. The aim of this research was to obtain a meta-analytical weighted effect size for the relationship between shallow probability discounting (the tendency to overvalue reinforcement with lower odds) and gambling intensity and to examine whether a gambling diagnosis moderated this effect size such that the relationship is stronger for diagnosed problem gamblers. METHODS: A database search identified studies that (a) measured both probability discounting and gambling and (b) reported statistical results allowing calculation of an effect size for meta-analysis. The search resulted in 12 studies reporting statistical results for probability discounting and gambling. The studies comprised 1685 individuals from different cohorts and nations, and included gamblers and non-gamblers. The studies reported 18 effect sizes. Across studies, gambling severity was assessed through diagnosis and gambling intensity was assessed through self-report and performance. Comprehensive Meta Analysis software calculated the weighted effect size and moderating role of gambling diagnosis. RESULTS: Shallower probability discounting was associated with greater gambling severity or intensity in all 12 studies. Throughout the studies, the weighted meta-analytical effect size for the connection between probability discounting and gambling was significant, with Hedges' g = 0.36 [standard error (SE) = 0.07, 95% confidence interval (CI) = 0.21, 0.50), P < 0.001]. Addressing the second aim of the study, individuals diagnosed with a gambling disorder or problem gambling compared with not diagnosed individuals showed an effect size of Hedges' g = 0.79 (SE = 0.18, 95% CI = 0.45, 1.14) and a moderation analysis indicated that this type of comparison showed significantly stronger effects than effect sizes based on associations between probability discounting and gambling (Q(1) = 7.80, P = 0.005). CONCLUSIONS: There appears to be a positive association between problem gambling and shallow probability discounting (a cognitive bias that overvalues low probability gains and/or undervalues high probability losses).

ABSTRACT

A number of studies have investigated the impact of mindfulness-based interventions on symptoms of post-traumatic stress (PTSD) compared to control conditions. The current meta-analysis consolidated findings from 18 studies reporting results for 21 samples of participants. Across studies, mindfulness-based treatments compared to control conditions were effective in ameliorating symptoms of PTSD, with Hedges' g=-0.44. Hedges' g was -0.59 for comparison of mindfulness-based interventions to waitlist control conditions. Changes in mindfulness may underpin the effect of mindfulness-based interventions on PTSD symptoms and thus the meta-analysis examined findings regarding increases in mindfulness. The 12 studies that assessed mindfulness found that the interventions significantly increased mindfulness, Hedges' g=0.52. Moderator analyses indicated that interventions with longer mindfulness training were more efficacious in reducing symptoms of PTSD. Across studies, gender, age, veteran status, or length of time between the intervention and assessment of PTSD symptoms did not moderate the impact of mindfulness-based interventions. The results provide a foundation for future research directions and have implications for work with those impacted by trauma.

ABSTRACT

This study examined the effects of virtual contact with nature on positive and negative affect, and investigated the psychological process of perceived restorativeness as a mediator of this relationship. A sample of 220 Australians aged between 18 and 75 years (M = 49.07, SD = 14.34, female = 72%) participated in the study. Participants were randomly allocated to one of the three experimental conditions experienced through video presentations: (1) 'wild' nature, (2) 'urban' nature, and (3) non-nature control. They then completed measures of perceived restorativeness as well as positive and negative affect. Compared to the non-nature control condition, the experience of wild nature resulted in significantly higher levels of positive affect and lower levels of negative affect. The experience of urban nature resulted in significantly lower levels of negative affect only compared to the non-nature control video. Experience of wild and urban nature resulted in greater perceptions of restorativeness as compared to the non-nature control video. Restorativeness was a significant underlying psychological mediating path through which nature experience exerted its influence on affect. These results have the potential to inform nature-based green care interventions for mental health as well as for urban planning to maximize beneficial effects of natural environments.

ABSTRACT

This meta-analysis examined the association between the level of childhood psychosocial stressors and telomere length, an important health biomarker. The meta-analysis, including 27 samples and 16,238 participants, found a significant association of -0.08 between a higher level of childhood stressors and shorter telomere length at a mean age of 42 across studies. Moderator analyses showed a trend in the direction of effect sizes being significantly larger with shorter times between the stressors and telomere measurement. Moderator analyses showed significantly higher effect sizes for studies that used a categorical method for assessing child stressor level and for assays completed with qPCR rather than with the Southern blot method. There was no significant moderation of effect size by whether study assayed leukocytes or buccal cells, whether the study assessed child stressor level by memory-based recall versus archival records, and whether the study controlled for age, sex, or additional variables. The results, focused on childhood events, add to prior findings that perceived stress and negative emotions are associated with telomere length.

ABSTRACT

This paper describes a model focused on the role of self-efficacy and belief in changeability of behavior in motivating environmentally sustainable behavior. The model was tested in two studies. The first study found that participants who had greater self-efficacy for sustainability behavior and a greater belief in their changeability of sustainability behavior had a higher level of approach motivation toward sustainability behavior and reported more such actual behavior. The second study investigated the effect of brief interventions intended to increase perception of self-efficacy for sustainability-related purchasing and changeability of sustainability-related purchasing. The intervention that focused on enhancing self-efficacy for making sustainability-related purchases had the strongest impact on intention to purchase. These findings have implications for interventions intended to change behavior related to environmental sustainability.

ABSTRACT

BACKGROUND AND OBJECTIVES: Telomeres are protective caps at the ends of chromosomes, and shorter telomeres are associated with poor physical health. The present study set out to consolidate the varying effect sizes found so far in studies of anxiety and telomere length. DESIGN AND METHODS: A meta-analytic investigation of the relationship between anxiety and telomere length used information from 17 different samples comprising a total of 19,424 participants. RESULTS: The results showed a small but significant association, r = -.06, between higher anxiety and shorter telomeres. Studies comparing individuals diagnosed with an anxiety disorder with other individuals had a significant effect size, and studies that did not use this comparison threshold did not have a significant effect size. CONCLUSIONS: Anxiety is associated with an important biomarker related to health. Future experimental studies that examine the impact of interventions intended to reduce anxiety in conjunction with measurement of telomere length can further clarify the impact of anxiety on telomere length.
