Psychometric properties of the Wolpe-Lazarus assertiveness scale with community-dwelling older adults

The psychometric properties of the Wolpe-Lazarus Assertiveness Scale (WLAS) were examined with an older community-dwelling, nonclinical, adult population. Three hundred twenty-seven older adults (ages, 57–96; mean, 75.68) who were not psychiatrically impaired completed a demographic questionnaire and the WLAS. Fifty-seven of the 327 subjects also filled out the WLAS on a repeated basis after 3 or 4 weeks in order to determine the test-retest reliability. Results indicate that the WLAS has an adequate internal consistency (Cronbach's=.75) and test-retest reliability (r=.81). WLAS cutoff scores of 14 and under identify unassertiveness. Older adults who are (1) African-American or (2) of lower SES tend to be significantly less assertive. Also, five factors emerged from a principal-components analysis accounting for 34.7% of the total variance.This research is based on the senior author's doctoral dissertation in partial fulfillment of the Ph.D. under the direction of the second, third, and fourth authors.

Psychometric evaluation of the situation test of heterosocial skill

This study examined various psychometric properties of Forms A and B of the Situation Test, developed by Rehm and Marston (Journal of Consulting and Clinical Psychology, 1968, 37, 565–574) for the assessment of heterosocial skill and anxiety. A third test form composed of heterosocially irrelevant items was also examined for comparison purposes. Split-half, alternate-form, and interresponse consistency was determined for measures of skill, anxiety, response latency, and response duration. Differences across test forms on these measures were also investigated. Subsequently, criterion-related validity was examined relative to three criteria of heterosocial skill. Results indicated that two measures, anxiety and response duration, displayed adequate internal consistency, while that of skill and response latency was marginal. Interresponse consistency was moderately low for all three test forms. Comparisons of mean performances across forms revealed significant differences, with heterosocially irrelevant items appearing easier, in general, than the heterosocial items of Forms A and B. Lastly, significant predictions of peer-reported heterosocial behavior were obtained for all three test forms, but two self-report criteria were not found to be related to test behavior. Various implications of these findings are discussed.Portions of this research were completed while the authors were affiliated with the University of Georgia, Athens, Georgia.

Accounting for Missing Correlation Coefficients in Fixed-Effects MASEM

Meta-analytic structural equation modeling (MASEM) is increasingly applied to advance theories by synthesizing existing findings. MASEM essentially consists of two stages. In Stage 1, a pooled correlation matrix is estimated based on the reported correlation coefficients in the individual studies. In Stage 2, a structural model (such as a path model) is fitted to explain the pooled correlations. Frequently, the individual studies do not provide all the correlation coefficients between the research variables. In this study, we modify the currently optimal MASEM-method to deal with missing correlation coefficients, and compare its performance with existing methods. This study is the first to evaluate the performance of fixed-effects MASEM methods under different levels of missing correlation coefficients. We found that the often used univariate methods performed very poorly, while the multivariate methods performed well overall.     

Rheumatoid arthritis is associated with negatively variable impacts on domains of female sexual function: evidence from a systematic review and meta-analysis

To systematically review the literature to identify the impact of rheumatoid arthritis (RA) on specific female sexual function domains. A meta-analysis was performed and the related literature were searched in MEDLINE, EMBASE, Cochrane Library, CNKI, CBM and Web of Science databases, and in reference lists of articles and systematic reviews. Score of the Female Sexual Function Index (FSFI) was used as the outcome measurement, and mean differences (MD) with 95% confidence intervals (CI) were calculated. Five studies were included, including 346 women with RA and 237 healthy female controls. Each domain of the FSFI score: lubrication (MD, ?2.48; 95% CI, ?3.69, ?1.28), orgasm-1.71 (?2.09, ?1.33), sexual desire-1.27 (?1.59, ?0.95), satisfaction-1.67 (?2.18, ?1.16), arousal-1.83 (?2.85, ?0.82), pain-1.57 (?2.43, ?0.70) and the total score ?8.84 (?11.88, ?5.79) were lower in RA women than healthy controls. Furthermore, lubrication dimension was most severely affected especially. This meta-analysis showed that female RA patients scored lower in each dimension of FSFI, mostly in the lubrication domain. It demonstrated that targeted interventions should be done to improve their sexual function. Future well-designed researches with larger sample sizes are necessary to evaluate the potential risk factors which determine female sexual dysfunction.     

Modelling the effect of worship attendance and personal prayer on spiritual well-being among 9- to 11-year-old students attending Anglican church schools in Wales

This study employs a modified form of the Fisher 16-item Feeling Good, Living Life measure of spiritual well-being (assessing quality of relationships across four domains: self, family, nature and God) among a sample of 1,328 students drawn from year five and year six classes within Church in Wales primary schools, alongside measures of frequency of worship attendance and frequency of personal prayer. The data demonstrate frequency of personal prayer is a much stronger predictor than frequency of worship attendance in respect of spiritual well-being. This finding is consistent with the view that personal prayer is a key factor in the formation of individual spirituality.     

Internet-based vs. face-to-face cognitive behavior therapy for psychiatric and somatic disorders: an updated systematic review and meta-analysis

During the last two decades, Internet-delivered cognitive behavior therapy (ICBT) has been tested in hundreds of randomized controlled trials, often with promising results. However, the control groups were often waitlisted, care-as-usual or attention control. Hence, little is known about the relative efficacy of ICBT as compared to face-to-face cognitive behavior therapy (CBT). In the present systematic review and meta-analysis, which included 1418 participants, guided ICBT for psychiatric and somatic conditions were directly compared to face-to-face CBT within the same trial. Out of the 2078 articles screened, a total of 20 studies met all inclusion criteria. Results showed a pooled effect size at post-treatment of Hedges g = .05 (95% CI, ?.09 to .20), indicating that ICBT and face-to-face treatment produced equivalent overall effects. Study quality did not affect outcomes. While the overall results indicate equivalence, there have been few studies of the individual psychiatric and somatic conditions so far, and for the majority, guided ICBT has not been compared against face-to-face treatment. Thus, more research, preferably with larger sample sizes, is needed to establish the general equivalence of the two treatment formats.

The Trait Anxiety Scale for Children: A validation study for European Portuguese children and adolescents

The State-Trait Anxiety Inventory for Children is a self-report instrument inspired on the State-Trait theory extended by Spielberger that measures a momentary state of anxiety (state) and a stable tendency to experience anxiety (trait). This study presents an exploratory adaptation of the Trait Scale and provides its psychometric properties for European Portuguese children and adolescents. The influence of sex and age were also explored. Our sample, composed of 402 participants aged 8–14 years, revealed a mean anxiety value of 28.37 (SD = 5.99). As expected, females revealed higher levels of anxiety than boys. Higher anxiety was obtained in our youngest group as compared to the oldest group. The exploratory factor analysis led to retaining only 16-items that presented acceptable adjustment to a one-factorial solution. Good indexes were obtained in the confirmatory analysis. The results also revealed good internal consistency and good test-retest reliability. Our results provide initial evidence that this scale is adequate to measure trait-anxiety in European Portuguese young people.     

Mindfulness-based interventions in the workplace: An inclusive systematic review and meta-analysis of their impact upon wellbeing

ABSTRACT

Given the demanding nature of many professions, efforts are ongoing to develop initiatives to improve occupational wellbeing, including mindfulness-based interventions (MBIs). To assess the efficacy of MBIs, meta-analytic procedures were conducted on 35 randomized controlled trials derived from an earlier inclusive systematic literature search (covering all occupations, MBIs, and wellbeing-related outcomes). Mindfulness had moderate effects on deficit-based outcomes such as stress (SMD = ?0.57), anxiety (SMD = ?0.57), distress (SMD = ?0.56), depression (SMD = ?0.48), and burnout (SMD = ?0.36), and moderate to small effects on asset-based outcomes like health (SMD = 0.63), job performance (SMD = 0.43), compassion and empathy (SMD = 0.42), mindfulness (SMD = 0.39), and positive wellbeing (SMD = 0.36), while no effects were observed for emotional regulation. However, the quality of the studies was inconsistent, suggesting more high-quality randomised controlled trials are needed.
