Personal growth initiative across the life span: a systematic review protocol of quantitative studies using the Personal Growth Initiative Scale-II.

BACKGROUND: Personal Growth Initiative (PGI) a multi-dimensional construct, conceptualised as a skill set that helps individuals to intentionally grow is considered an important construct throughout the life span. Coping with the challenges, transitions, experiences and stressors of life requires an active growth orientation. In previous empirical research, the construct has been measured by either the PGIS-I or PGIS-II, of which only the latter takes account of the theoretically established multi-dimensionality of the construct. This paper describes the protocol for conducting a systematic review of published peer-reviewed empirical research articles on the multi-dimensional construct of PGI. The aim of this review is threefold: (1) to better understand the multi-dimensional construct PGI in different contexts and populations, (2) to improve our understanding of the reliability and validity of the PGIS-II in various research populations and (3) to obtain an overview of its associations with relevant psychosocial factors. METHODS: For the development of this protocol, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) reporting guidelines were used. Four databases and one registry will be searched using a predetermined search strategy for relevant studies. Studies will be screened, by two reviewers independently, against the established inclusion criteria. During the data extraction process, the quality of the included studies will be assessed using the Quality Assessment for Survey Studies in Psychology (Q-SSP). The collected data will then be analysed and reported in both narrative and tabular form according to the PRISMA 2020 statement guidelines and flow diagram. DISCUSSION: The findings of this study will increase our understanding of the dynamics of PGI throughout the lifespan, its associations with other psychosocial factors and the psychometric properties of the PGIS-II. It will also clarify where additional research is needed. The objectives of the proposed review can provide a basis for the development of practical applications and interventions.

Staying connected in old age: associations between bonding social capital, loneliness and well-being and the value of digital media.

OBJECTIVES: We examined associations between age, bonding social capital (BSC), loneliness and psychological, social and emotional well-being in old age. As in theory digital media can support both preservation of and access to someone's social capital, we also explored associations between the use of WhatsApp, social network sites (SNS) and Internet applications and respectively BSC and loneliness. METHOD: In this cross-sectional study a sample of 349 older adults (range = 70y-93y; Mean(SD)=74.8y(4.9y); 59.6% male) filled out a questionnaire including the bonding social capital subscale of the personal social capital scale for elderly (PSCSE), validated scales measuring social, emotional, and psychological well-being and loneliness, the SNS intensity scale and items measuring frequencies of Whatsapp use and use of various Internet functions. Also relevant demographic and other covariates were included. RESULTS: Regression analyses including relevant covariates confirmed our hypotheses, finding negative associations between BSC and both age and loneliness, and positive associations between BSC and psychological, social and emotional well-being. WhatsApp and Internet use were both found positively associated with BSC, whilst a negative association between WhatsApp use and loneliness was found. SNS use was not associated with BSC nor with loneliness. CONCLUSION: Our findings indicate BSC as an important factor in positive aging and illustrate a widening gap between the need for socio-emotional resources versus their availability. With regard to digital media, we conclude that its value in old age should be sought in providing access to one's bonding social capital rather than adding to it by expanding the number of social relations.

Longitudinal measurement invariance of the Working Alliance Inventory - Short form across coaching sessions.

BACKGROUND: Throughout the psychotherapeutic and coaching literature, the client-therapist or coach-coachee working alliance has been highlighted as key force driving positive outcome. The Working Alliance Inventory Short form (WAI-S) for coaching charts the quality of working alliance throughout coaching sessions and is broadly applied in coaching research. Due to a shortfall in research on psychometric properties of the WAI-S, the purpose of this study was to examine (a) if the theorized three-factor structure of the 12-item WAI-S forms a solid representation of the dimensions of working alliance in coaching, and (b) longitudinal measurement invariance (LMI) of the WAI-S. METHOD: Data were collected in a two-wave study design comprising a main study sample of N = 690 Dutch coachees that completed the questionnaire at the first measurement, of which N = 490 also completed the questionnaire at the second measurement. Post hoc sensitivity analysis was performed based on the original sample, lacking additional information on covariates, and included both completers and dropouts, comprising N = 1986 respondents at T1, and N = 1020 respondents at T2. RESULTS: Confirmatory factor analyses evidenced best fit of the three-factor model in comparison to one-, and two-factor models at both time points. Despite the fact that multigroup confirmatory factor analysis detected non-invariant intercepts, our findings overall supported measurement invariance across coaching sessions. CONCLUSIONS: As decisions in both clinical and scientific practices generally rely on outcome assessment of interpersonal change in scores on the same measure over time, we believe our findings to be of contributing value to the consolidation of interpretation and accuracy of scorings on the WAI-S in coaching.

Prospective associations between working alliance, basic psychological need satisfaction, and coaching outcome indicators: a two-wave survey study among 181 Dutch coaching clients.

BACKGROUND: The coach-coachee working alliance and coachee motivation seem important factors for achieving positive coaching results. Self-determination theory, specifically basic psychological need theory, has been proposed as a relevant framework for understanding these relationships. The current longitudinal survey study therefore investigates prospective associations between coachees' appraisal of the working alliance, basic psychological need satisfaction, and the coaching outcome indicators goal attainment, wellbeing, absence of psychopathology, and personal growth initiative. METHODS: The sample (N = 181) consisted of Dutch coachees that were recruited across a range of coaching settings and contexts. Online self-report questionnaires were administered twice (T0 and T1), with an intervening time of 3 weeks, assessing working alliance, basic psychological need satisfaction, goal attainment, wellbeing, absence of psychopathology, and personal growth initiative. Parallel analysis with Monte Carlo simulations and confirmatory factor analyses were performed to assess the dimensionality of working alliance and basic psychological need satisfaction scores. Multiple regression analyses (stepwise) were used to examine prospective (T0 to T1) associations between working alliance and basic psychological need satisfaction, and their association with outcome indicators. RESULTS: The coachees' perception of the working alliance was positively and reciprocally, although modestly, associated with basic psychological need satisfaction. In addition, both working alliance and basic psychological need satisfaction were prospectively associated with goal attainment, but not with other outcome indicators. CONCLUSIONS: Results provide tentative support for a role of basic psychological need satisfaction in facilitating the establishment of a good working alliance. Additionally, the perception of a good quality, need supportive relationship with the coach appears to be associated with better goal achievement, but not with other outcome indicators. Associations were generally modest, and more research is needed to better measure and comprehend the unique contributions of specific relational and motivational factors to outcomes in coaching and assess the robustness of the current study findings.

Companion Animals as Buffer against the Impact of Stress on Affect: An Experience Sampling Study.

Companion animals have been identified as a unique source of social support and as contributors to mental wellbeing. This study uses the Experience Sampling Method to test whether this effect is due to stress-buffering. A total of 159 dog and cat owners responded to a series of randomly scheduled questionnaires on their smartphones. At each measurement moment, they reported in whether a pet is present at that moment and to what extent they have interacted with the pet. They also reported on stressful activities and events and on their current positive (PA) and negative (NA) affect. Multilevel regression analyses showed that when a companion animal was present (vs. absent) the negative association between stress and PA is less pronounced (event stress: B = 0.13, p = 0.002, 95% CI = 0.05; 0.21 activity stress: B = 0.08, p < 0.001, 95% CI = 0.04; 0.12). No additional main effect was revealed when tested in a subsample of records that reported low or no stress. Main effects were found for the presence of a companion animal on negative affect (B = 0.08, p < 0.001; 95% CI = 0.12; 0.05) and for interacting with a companion animal on positive affect (B = 0.06, p < 0.001; 95% CI = 0.04; 0.08). This shows that the presence of a companion animal buffers against the negative consequences of stress on positive affect, indicating stress-buffering as a mechanism behind the pet-effect. It is, however, not the only mechanism and more research is required to further elucidate how companion animals contribute to human wellbeing.

Optimism and Mental Health in Adolescence: a Prospective Validation Study of the Dutch Life-Orientation Test-Revised (LOT-R-A) for Adolescents.

The study aimed to examine the psychometric properties of the Dutch Life Orientation Test-Revised for Adolescents (LOT-R-A), a self-report questionnaire assessing dispositional optimism, and to evaluate the two-factor structure (optimism, pessimism). The LOT-R-A and the questionnaires measuring well-being (MHC-SF-A) and psychological problems (SDQ) were completed by 459 Dutch adolescents (178 boys and 281 girls) between the ages of 11 and 18 years at baseline and 281 adolescents at a four-week follow-up. The results confirmed the two-factor structure (optimism, pessimism) of the LOT-R-A. The findings provided evidence of internal consistency of scores ranging from low to good, and evidence of good test-retest reliability of scores. Further, scores of optimism were cross-sectionally positively associated with scores of positive emotions and well-being and negatively with scores of psychological problems and negative emotions, providing evidence of convergent and divergent validity of optimism scores with emotions, well-being, and psychological problems. Lastly, scores of optimism were prospectively positively associated with scores of well-being and negatively with scores of psychological problems, providing evidence of criterion validity of optimism scores with well-being and psychological problems. Based on these findings it can be concluded that the LOT-R-A is a valid instrument to examine optimism among adolescents. Future research can help to elucidate the role of optimism in mental health interventions and can gather knowledge on how these interventions can be refined to optimally cultivate optimism during the developmental period of adolescence.

The association between specific activity components and depression in nursing home residents: the importance of the social component.

OBJECTIVES: To longitudinally explore the association between activities and depressive symptoms of nursing home (NH) residents, taking into account that each activity may contain multiple components (physical, creative, social, cognitive, and musical). METHOD: Study with a baseline and two follow-ups (four and eight months). Participants were forty physically frail residents of four NHs in the Netherlands. Residents were interviewed about depressive symptoms (CES-D) and activities they conducted over the previous week. Three researchers independently rank ordered each activity on the degree to which it could be regarded as having physical, creative, social, cognitive, and musical components. Accounting for the rank score and the time the resident spent on that activity, residents were categorized per activity component into four levels: absent, low, medium, and high. RESULTS: Mixed models predicting depressive symptoms from individual activity components showed significant associations for the social and cognitive components. Compared with the lowest activity level, the analyses showed fewer depressive symptoms for all higher levels of the social and cognitive components. However, a mixed model adjusted for all activity components showed no unique effect of the cognitive component or other components, while the effects of the social component remained significant. The analyses did not show differences between the time points. CONCLUSION: The results suggest that the effects of activities on depressive symptoms might be mainly explained by their social component. It is, thus, important to always stimulate social involvement and interaction when developing and applying depression interventions. However, intervention research is needed to confirm these findings.

Gratitude and loneliness in adults over 40 years: examining the role of psychological flexibility and engaged living.

OBJECTIVES: The aim of the present study was to investigate the association between trait gratitude and loneliness in a Dutch population sample of adults over 40 years. In addition, the mediating role of psychological flexibility and engaged living between trait gratitude and loneliness was assessed. METHOD: A total sample of 163 adults of which 65 men (40%) and 98 women (60%) between 41 and 92 years (Mage = 66, SDage = 12) participated in this study. Data from the Loneliness Questionnaire, Flexibility Index Test, Engaged Living Scale and the Short Gratitude, Resentment, and Appreciation Test were used. Mediation analysis was performed. RESULTS: Analysis showed a negative association between trait gratitude and loneliness. In addition, after adjusting for the demographic variables age, gender and educational level, the association between trait gratitude and loneliness was fully mediated by psychological flexibility, and partially mediated by engaged living. CONCLUSION: This study endorses the importance of trait gratitude and psychological flexibility in relation to experiencing loneliness. Further research is needed to replicate these findings in a more diverse sample and to investigate the causal relationships between these constructs. It would also be interesting to further investigate the role of different age groups and goal (dis)engagement strategies in this relation.

Bonding personal social capital as an ingredient for positive aging and mental well-being. A study among a sample of Dutch elderly.

OBJECTIVES: The current study aims to add to the limited empirical research of possible benefits of personal social capital for the well-being of elderly. A validated personal social capital scale, measuring both bonding and bridging social capital in a general population, was adjusted to fit the characteristics of the social environment of elderly, to explore the association between social capital and well-being of elderly, as well as the mediating role of loneliness. METHOD: A sample of 328 Dutch adults, varying in age from 65 to 90 years (Mean = 72.07; SD = 4.90) filled out an online questionnaire including the adapted personal social capital scale for elderly (PSCSE), as well as validated scales measuring social, emotional, and psychological well-being and loneliness. Relevant other (demographic) variables were included for testing construct and criterion validity. RESULTS: CFA analysis revealed the subdimensions bonding and bridging social capital with reliability scores of respectively α = .88 and α = .87, and α = .89 for the total scale. Regression analyses confirmed construct and criterion validity. Subsequently, significant positive associations between bonding social capital and respectively social, emotional and psychological well-being were found. These associations were mediated by loneliness. Bridging social capital was only found to be significantly associated with social well-being, not mediated by loneliness. CONCLUSION: Our findings have enhanced our understanding of the association between social capital and mental well-being of elderly and indicate that bonding personal social capital in particular may be considered an ingredient for positive aging.

Cultural differences in positive psychotic experiences assessed with the Community Assessment of Psychic Experiences-42 (CAPE-42): a comparison of student populations in the Netherlands, Nigeria and Norway.

BACKGROUND: Previous studies have suggested that culture impacts the experience of psychosis. The current study set out to extend these findings by examining cultural variation in subclinical positive psychotic experiences in students from The Netherlands, Nigeria, and Norway. Positive psychotic experiences were hypothesized to (i) be more frequently endorsed by, and (ii) cause less distress in Nigerian vs. Dutch and Norwegian students. METHODS: Psychology students, aged 18 to 30 years, from universities in the Netherlands (n = 245), Nigeria (n = 478), and Norway (n = 162) were assessed cross-sectionally with regard to the frequency of subclinical positive psychotic experiences and related distress, using the Community Assessment of Psychic Experiences (CAPE-42). Multi-group confirmatory factor analysis and multivariate analysis of covariance were performed to assess measurement invariance of the positive symptom dimension (CAPE-Pos) and compare mean frequency and associated distress of positive psychotic experiences across study samples. RESULTS: Only CAPE-Pos items pertaining to the dimensions 'strange experiences' and 'paranoia' met assumptions for (partial) measurement invariance. Frequencies of these experiences were higher in the Nigerian sample, compared to both the Dutch and Norwegian samples, which were similar. In addition, levels of experience-related distress were similar or higher in the Nigerian sample compared to respectively the Dutch and Norwegian samples. CONCLUSION: Although positive psychotic experiences may be more commonly endorsed in non-Western societies, our findings do not support the notion that they represent a more benign, and hence less distressing aspect of human experience. Rather, the experience of psychotic phenomena may be just as, if not more, distressing in African than in European culture. However, observed differences in CAPE-Pos frequency and distress between samples from different cultural settings may partly reflect differences in the measure rather than in the latent trait. Future studies may therefore consider further cross-cultural adaptation of CAPE-42, in addition to explicitly examining cultural acceptance of psychotic phenomena, and environmental and other known risk factors for psychosis, when comparing and interpreting subclinical psychotic phenomena across cultural groups.

An fMRI study into emotional processing in Parkinson's disease: Does increased medial prefrontal activation compensate for striatal dysfunction?

BACKGROUND: Apart from a progressive decline of motor functions, Parkinson's disease (PD) is also characterized by non-motor symptoms, including disturbed processing of emotions. This study aims at assessing emotional processing and its neurobiological correlates in PD with the focus on how medicated Parkinson patients may achieve normal emotional responsiveness despite basal ganglia dysfunction. METHODS: Nineteen medicated patients with mild to moderate PD (without dementia or depression) and 19 matched healthy controls passively viewed positive, negative, and neutral pictures in an event-related blood oxygen level-dependent functional magnetic resonance imaging study (BOLD-fMRI). Individual subjective ratings of valence and arousal levels for these pictures were obtained right after the scanning. RESULTS: Parkinson patients showed similar valence and arousal ratings as controls, denoting intact emotional processing at the behavioral level. Yet, Parkinson patients showed decreased bilateral putaminal activation and increased activation in the right dorsomedial prefrontal cortex (PFC), compared to controls, both most pronounced for highly arousing emotional stimuli. CONCLUSIONS: Our findings revealed for the first time a possible compensatory neural mechanism in Parkinson patients during emotional processing. The increased medial PFC activity may have modulated emotional responsiveness in patients via top-down cognitive control, therewith restoring emotional processing at the behavioral level, despite striatal dysfunction. These results may impact upon current treatment strategies of affective disorders in PD as patients may benefit from this intact or even compensatory influence of prefrontal areas when therapeutic strategies are applied that rely on cognitive control to modulate disturbed processing of emotions.

"Keep your brain fit!" Effectiveness of a psychoeducational intervention on cognitive functioning in healthy adults: A randomised controlled trial.

A psychoeducational intervention (Keep your brain fit!) was designed for the middle-aged and older working population. The intervention focuses on increasing knowledge and awareness about cognitive ageing and teaching strategies to cope with cognitive changes. The primary aim of this study was to investigate the effectiveness of the e-health intervention in terms of subjective cognitive functioning. As secondary aims, objective cognitive functioning and psychological well-being were also measured. A randomised controlled trial that included people aged 40 to 65 years was conducted. A maximum of 4 weeks was allowed to complete the intervention. The outcome measures were obtained from an online test battery that was administered at baseline, post-test and at 4-week follow-up. A total of 376 participants completed the whole study. After the intervention, the experimental group reported more feelings of stability concerning memory functioning and perceived greater locus of control over memory compared to the control group. These effects were maintained at the 4-week follow-up. Taking into account the relatively low costs and easy accessibility of this e-health intervention, we consider the programme to be a valuable contribution to public healthcare interventions for middle-aged and older adults.

Cognitive interventions in healthy older adults and people with mild cognitive impairment: a systematic review.

Given that the research area of cognitive intervention studies in the aging population is growing rapidly, it is important to review and gauge more recent intervention studies, in order to determine the evidence for the effectiveness of cognitive interventions. The purpose of the present review was to update the recent systematic reviews of Papp et al. (2009) and Martin et al. (2011), to evaluate the effectiveness of cognitive interventions in healthy older adults and people with MCI, by taking into account the methodological quality of the interventions studies. A systematic review of randomized controlled trials (RCT) and clinical studies published between August 2007 and February 2012 in Pubmed and PsychINFO was performed. The quality of the included RCTs was assessed according to the CONSORT criteria for RCTs. A total of thirty-five studies were included; twenty-seven RTCs and eight clinical studies. The content of the intervention studies differed widely, as did the methodological quality of the included RCTs, but was considerably low with an average of 44% of the Consort items included. The results show evidence that cognitive training can be effective in improving various aspects of objective cognitive functioning; memory performance, executive functioning, processing speed, attention, fluid intelligence, and subjective cognitive performance. However, the issue whether the effects of cognitive interventions generalize to improvement in everyday life activities is still unresolved and needs to be addressed more explicitly in future research.

Validation of diagnostic criteria for apathy in Parkinson's disease.

BACKGROUND: Apathy is a common neuropsychiatric syndrome in Parkinson's Disease (PD) that affects quality of life. Research into apathy has been hampered by a lack of broadly accepted diagnostic criteria. Recently, diagnostic criteria for apathy in neuropsychiatric disorders have been proposed, which to date have not been validated in PD. AIM: To validate the proposed diagnostic criteria for apathy in PD. DESIGN AND METHODS: In a cross-sectional study, outpatients with PD visiting a movement disorders clinic underwent a protocolized assessment of motor function, activities of daily living (ADL), cognition and mood. In addition, the diagnostic criteria for apathy were administered as well as two apathy rating instruments: the Lille Apathy Rating Scale (LARS) and the apathy section of the Neuropsychiatric Inventory (NPI). RESULTS: Of the included patients 17.2% were diagnosed with apathy according to the criteria. Acceptability and internal consistency of the criteria was good, as was the concurrent validity with the LARS and apathy section of the NPI. Discriminant validity of the criteria with depression was moderate to good. All domains of criterion B (behavior, cognition, emotion) contributed to the diagnosis of apathy, of which reduced goal-directed behavior was the most frequently observed symptom. CONCLUSION: The recently proposed diagnostic criteria for apathy are useful in clinical practice and in research with PD patients with and without cognitive impairment.

Neuroanatomical correlates of apathy in Parkinson's disease: A magnetic resonance imaging study using voxel-based morphometry.

Apathy is generally defined as a disorder of motivation and is considered one of the most common neuropsychiatric disturbances in Parkinson's disease (PD). Only few studies addressed the neuroanatomical correlates of apathy in PD. The aim of this article was to determine the structural correlates of apathy in PD patients. Fifty-five PD patients underwent a neuropsychiatric and neuropsychological examination, and a 3 T magnetic resonance imaging scan was acquired. A voxel-based multiple regression analysis was used to calculate correlation between gray matter density and severity measures of apathy. Apathy correlates with decreased cognitive functioning and more depressive symptoms but not with more severe motor symptoms. High apathy scores were correlated with low gray matter density values in a number of cortical brain areas: the bilateral precentral gyrus (BA 4, 6), the bilateral inferior parietal gyrus (BA 40), the bilateral inferior frontal gyrus (BA 44, 47), the bilateral insula (BA 13), the right (posterior) cingulate gyrus (BA 24, 30, 31), and the right precuneus (BA 31). Apathy in PD correlates with reduced gray matter density in a number of brain regions. The involvement of the cingulate gyrus and inferior frontal gyrus is in line with the results of earlier studies addressing apathy in patients with Alzheimer's disease or depressive disorder. Further studies addressing the pathogenesis of apathy are needed.

Assessment of depression in Parkinson's disease: the contribution of somatic symptoms to the clinimetric performance of the Hamilton and Montgomery-Asberg rating scales.

OBJECTIVE: To assess the influence of somatic symptoms of the Hamilton Depression Rating Scale (HAMD) and Montgomery-Asberg Depression Rating Scale (MADRS) on the clinimetric performance of these scales in patients with Parkinson's disease (PD). METHODS: A total of 224 patients underwent a protocolized mental status examination, consisting of the Structured Clinical Interview for DSM-IV depressive disorder (SCID-D), as well as the HAMD and MADRS. Sensitivity, specificity, positive, and negative predictive values for a range of cut-off scores were calculated for both rating scales and for modified versions of these scales in which all somatic items were eliminated. In addition, receiver operating characteristic (ROC) curves were obtained for both the modified and unmodified scales. RESULTS: Elimination of the somatic items of depression from the HAMD and MADRS resulted in a reduced specificity of both the HAMD and the MADRS, and an increased sensitivity of the MADRS. CONCLUSION: The authors recommend the full version of the HAMD and MADRS if used for diagnostic purposes; for screening purposes, the abbreviated version without somatic items can be used. Additional advantages of using full rating scales, with somatic items included, are that these provide more information on the severity of depression and allow for easier comparison across studies.

A systematic review of prevalence studies of depression in Parkinson's disease.

Prevalence rates of depressive disorders in Parkinson's disease (PD) vary widely across studies, ranging from 2.7% to more than 90%. The aim of this systematic review was to calculate average prevalences of depressive disorders taking into account the different settings and different diagnostic approaches of studies. Using Medline on Pubmed, a systematic literature search was carried out for studies of depression in Parkinson's disease. A total of 104 articles were included and assessed for quality; 51 articles fulfilled the quality criteria. Multiple publications from the same database were not included in the meta-analysis. In the remaining 36 articles, the weighted prevalence of major depressive disorder was 17% of PD patients, that of minor depression 22% and dysthymia 13%. Clinically significant depressive symptoms, irrespective of the presence of a DSM defined depressive disorder, were present in 35%. In studies using a (semi) structured interview to establish DSM criteria, the reported prevalence of major depressive disorder was 19%, while in studies using DSM criteria without a structured interview, the reported prevalence of major depressive disorder was 7%. Population studies report lower prevalence rates for both major depressive disorder and the clinically significant depressive symptoms than studies in other settings. This systematic review suggests that the average prevalence of major depressive disorder in PD is substantial, but lower than generally assumed.
