Development and Initial Validation of a General Psychological Well-being Scale (GPWS) in an African Context

This study aimed to develop and validate the General Psychological Well-being Scale (GPWS) in an African sample, based on the empirical overlap between hedonic and eudaimonic facets of well-being as found in previous research. The quantitative cross-sectional study was conducted in three phases: secondary data analysis (n = 2005), pilot study (n = 296) and main study (n = 459). The pilot and main study included the GPWS as well as other psychological well-being measures for criterion-related validity. The pilot study yielded satisfactory psychometric properties. The main study yielded a high, reliable Cronbach alpha of.89 and evidence of construct validity. The GPWS appears to be a unidimensional scale suitable for research use with Setswana-speaking people.     

Career Counselling: The Usefulness of the Career Interest Profile (CIP)

This study reports the findings from exploratory career counselling with Italian undergraduate university students using the Career Interest Profile (CIP). The participants (n = 178, females = 51.69%; mean age 22.28, SD = 1.59 years) received elective career counselling on campus. The students completed the CIP and the Self-Directed Search (SDS). Data were analyzed using both qualitative and quantitative approaches. The CIP yielded satisfactory results with regard to trustworthiness and intercorrelations with the SDS and provides career counsellors with a useful instrument for the identification of interest profiles of Italian undergraduate university students. Participants reported being enabled to explore prospective career interest areas using career-story narratives for constructing life trajectories and enhanced development of their career stories.     

A Systematic Review and Meta-Analysis on the Efficacy of Self-Help Interventions in Tinnitus

This study is a review and meta-analysis on the efficacy of cognitive-behavioural therapy (CBT) self-help interventions for tinnitus. Randomized controlled trials were identified by searching in databases (e.g. ISI Web of Knowledge, PubMed, Cochrane Library, and PSYNDEX) and by manual search. Ten studies with 1188 participants in total were included in the meta-analysis. Participants were 49.2 years old and had tinnitus for 5.2 years. Self-help interventions significantly reduced tinnitus distress (d = 0.48) and depressiveness (d = 0.25) when compared with a passive control (e.g. information only and discussion forums) at post-assessment. There was no difference to the face-to-face controls (group treatment). The presence of therapists and the methodological quality of the studies did not influence the results. Sensitivity analysis revealed that there might be a publication bias regarding the comparison to the face-to-face control. However, the results suggest that CBT self-help interventions are an effective treatment for tinnitus distress. Since few studies were identified, this conclusion must be supported by future meta-analyses.     

Mindfulness-based cognitive therapy for the treatment of current depressive symptoms: a meta-analysis

ABSTRACT

Mindfulness-based cognitive therapy (MBCT) appears to be a promising intervention for the prevention of relapse in major depressive disorder, but its efficacy in patients with current depressive symptoms is less clear. Randomized clinical trials of MBCT for adult patients with current depressive symptoms were included (k = 13, N = 1046). Comparison conditions were coded based on whether they were intended to be therapeutic (specific active controls) or not (non-specific controls). MBCT was superior to non-specific controls at post-treatment (k = 10, d = 0.71, 95% confidence interval [CI] [0.47, 0.96]), although not at longest follow-up (k = 2, d = 1.47, [?0.71, 3.65], mean follow-up = 5.70 months across all studies with follow-up). MBCT did not differ from other active therapies at post-treatment (k = 6, d = 0.002, [?0.43, 0.44]) and longest follow-up (k = 4, d = 0.26, [?0.24, 0.75]). There was some evidence that studies with higher methodological quality showed smaller effects at post-treatment, but no evidence that effects varied by inclusion criterion. The impact of publication bias appeared minimal. MBCT seems to be efficacious for samples with current depressive symptoms at post-treatment, although a limited number of studies tested the long-term effects of this therapy.     

The Universality of Childhood Emotional Abuse: A Meta-Analysis of Worldwide Prevalence

This comprehensive meta-analysis combined prevalence figures of child emotional abuse reported in 29 studies, including 46 independent samples with a total of 7,082,279 participants. The overall estimated prevalence was 3/1,000 for studies using informants and 363/1,000 for studies using self-report measures of child emotional abuse. Procedural factors seem to exert a greater influence on the prevalence of childhood emotional abuse than sample characteristics and definitional issues, without fully explaining the vast variation of prevalence rates reported in individual studies. We conclude that child emotional abuse is a universal problem affecting the lives of millions of children all over the world, which is in sharp contrast with the United Nation's Convention on the Rights of the Child.     

Affective, Continuance, and Normative Commitment to the Organization: A Meta-analysis of Antecedents, Correlates, and Consequences

The authors conducted meta-analyses to assess (a) relations among affective, continuance, and normative commitment to the organization and (b) relations between the three forms of commitment and variables identified as their antecedents, correlates, and consequences in Meyer and Allen's (1991) Three-Component Model. They found that the three forms of commitment are related yet distinguishable from one another as well as from job satisfaction, job involvement, and occupational commitment. Affective and continuance commitment generally correlated as expected with their hypothesized antecedent variables; no unique antecedents of normative commitment were identified. Also, as expected, all three forms of commitment related negatively to withdrawal cognition and turnover, and affective commitment had the strongest and most favorable correlations with organization-relevant (attendance, performance, and organizational citizenship behavior) and employee-relevant (stress and work-family conflict) outcomes. Normative commitment was also associated with desirable outcomes, albeit not as strongly. Continuance commitment was unrelated, or related negatively, to these outcomes. Comparisons of studies conducted within and outside North America revealed considerable similarity yet suggested that more systematic primary research concerning cultural differences is warranted.     

Associations between job burnout and self-efficacy: a meta-analysis

Background and Objectives: This study aimed at systematically reviewing and meta-analyzing the strength of associations between self-efficacy and job burnout (the global index and its components). We investigated whether these associations would be moderated by: (a) the type of measurement of burnout and self-efficacy, (b) the type of occupation, (c) the number of years of work experience and age, and (d) culture. Design and Methods: We systematically reviewed and analyzed 57 original studies (N?=?22,773) conducted among teachers (k?=?29), health-care providers (k?=?17), and other professionals (k?=?11). Results: The average effect size estimate for the association between self-efficacy and burnout was of medium size (?.33). Regarding the three burnout components, the largest estimate of the average effect (?.49) was found for the lack of accomplishment. The estimates of the average effect were similar, regardless of the type of measures of burnout and self-efficacy measurement (general vs. context-specific). Significantly larger estimates of the average effects were found among teachers (compared to health-care providers), older workers, and those with longer work experience. Conclusions: Significant self-efficacy–burnout relationships were observed across countries, although the strength of associations varied across burnout components, participants' profession, and their age.     

Revisiting the mediating role of leader–member exchange in transformational leadership: the differential impact model

Transformational leadership (TFL) has been proposed as an essential antecedent of leader–member exchange (LMX), which in turn affects outcomes in organizations. We extend this mediation hypothesis in two ways by proposing a differential impact model, which we test on three organizational outcomes: employee job satisfaction, employee organizational commitment, and leader effectiveness. First, we extend LMX’s mediational impact—which has previously only been tested for employee outcomes—to leader effectiveness. Second, we argue that this mediation will be stronger for outcomes that are more proximal rather than distal to dyadic relations between leader and followers (high proximity: job satisfaction; medium proximity: organizational commitment; low proximity: leader effectiveness). Meta-analytic structural equation modelling based on 132 studies revealed that LMX mediates TFL’s relationships with employee outcomes (more strongly for job satisfaction than for commitment), but not with leader effectiveness, whereas TFL showed a stronger direct link to leader effectiveness. The findings suggest that TLF and LMX contribute differentially to organizational outcomes depending on their proximity to dyadic relations between leaders and followers. The differential impact model uncovers leadership effectiveness processes, integrates influential leadership theories, and highlights the importance of distinguishing between different outcome measures and the processes facilitating them.     

Psychometric properties of the General Health Questionnaire-12 in a sample of Hong Kong employees

The General Health Questionnaire-12 (GHQ-12) is a widely used instrument for measuring psychological strain, but the factor structure of the GHQ-12 is inconclusive. The present study examined one-factor, two- and three-factor models of the GHQ-12 using structural equations modelling in a longitudinal data-set of Hong Kong employees. The findings supported a two-factor model consisting of a ‘Social Dysfunction’ factor measured by three items, and an ‘Anxiety/Depression’ factor measured by four items. Implications and limitations are discussed.     

An improved spatial span test of visuospatial memory

In the widely used Corsi Block Test and Wechsler Spatial Span Tests, participants must reproduce sequences of blocks in the order touched by the examiner until two trials are missed at the same sequence length. The examiner records either the maximum number of blocks correctly reported or the total number of correct lists. Here, we describe a computerized spatial span test (C-SST) that uses psychophysical procedures to quantify visuospatial mean span (MnS) with sub-digit precision. Results from 187 participants ranging in age from 18 to 82 years showed that accuracy declined gradually with list length around the MnS (by ～30% per item). Simulation studies revealed high variance and biases in CBT and Wechsler measures, and demonstrated that the C-SST provided the most accurate estimate of true span (i.e., the sequence length producing 50% correct). MnS declined more rapidly with age than mean digit span (MnDS) measured in the same participants. Response times correlated with both MnS and MnDS scores. Error analysis showed that omission and transposition errors predominated, with weaker primacy and recency effects in spatial span than digit span testing. The C-SST improves the precision of spatial span testing and reveals significant differences between visuospatial and verbal working memory.
