A psychometric investigation of the multiple-choice version of Animated Triangles Task to measure Theory of Mind in adolescence.

The Animated Triangles Task (AT) is commonly used to measure Theory of Mind (ToM). AT can be scored by clinicians based on participants' verbal responses (AT-verbal) or using a multiple-choice paradigm (AT-MCQ). This study aimed to evaluate the validity of the less time-consuming AT-MCQ. To do this, we examined agreement and correlations between the AT-MCQ and the original AT-verbal scores in 1546 adolescents from a population-based sample. As a supplementary analysis of known-groups validity, we examined if AT-MCQ was as sensitive as AT-verbal in detecting ToM-limitations in 54 adolescents with autism spectrum disorder (ASD), using register-data. The agreement between AT-verbal and AT-MCQ varied markedly across test items. Scores on the two scoring methods were weakly correlated. Both scoring methods weakly detected differences between adolescents with and without ASD in this population-based sample. Most participants had appropriate responses on both AT-MCQ and AT-verbal, which yielded overall acceptable agreement. However, the feasibility of using either scoring methods to measure ToM-limitations in adolescents from the general population is questionable.

Longitudinal associations of self-reported satisfaction with life and vitality with risk of mortality.

OBJECTIVE: The aims of the current study were to investigate the associations between two aspects of well-being - satisfaction with life and vitality - and all-cause mortality, and examine the impact of potential confounding factors on the associations. METHODS: Baseline satisfaction with life was assessed using the Satisfaction With Life Scale (n = 7058) and vitality was assessed using the Short-Form 36 vitality subscale (n = 6987). The study sample consisted of midlife participants from the Copenhagen Aging and Midlife Biobank (CAMB) study conducted from 2009 to 2011. Deaths (n = 312) in the study sample in the follow-up period (mean of 8.6 years) were assessed using Danish register data. The hazard ratios of all-cause mortality according to satisfaction with life and vitality scores adjusted for potential covariates were examined with proportional hazard regression. RESULTS: A one standard deviation increase on the SWLS and the SF-36 vitality scale was associated with a 39% (HR = 0.61, 95% CI = 0.55-0.67) and 40% (HR = 0.60, 95% CI = 0.54-0.66) decreased risk of mortality respectively, after adjustment for baseline sociodemographic factors. The associations remained significant after separate adjustment for lifestyle (SWLS: HR = 0.67, SF-36 vitality: HR = 0.67), health (SWLS: HR = 0.65, SF-36 vitality: HR = 0.64), depressive symptoms (SWLS: HR = 0.72, SF-36 vitality: HR = 0.71) and social factors (SWLS: HR = 0.76, SF-36 vitality: HR = 0.69). CONCLUSIONS: Satisfaction with life and vitality are of predictive value for mortality, independently of sociodemographics, lifestyle, health, depressive symptoms, and social factors.

Satisfaction with life and SF-36 vitality predict risk of ischemic heart disease: a prospective cohort study.

The main objective of the current study was to investigate associations between two aspects of well-being - satisfaction with life and vitality - and incidence of and mortality from ischemic heart disease. Study design. The Copenhagen Aging and Midlife Biobank (CAMB) was conducted from 2009 to 2011 and was used as baseline data with 6750 individuals having complete information on The Satisfaction with Life Scale (SWLS) and 6652 individuals with complete information on the Short Form Health Survey (SF-36) vitality scale. Incidence of and mortality from ischemic heart disease were assessed using Danish register data and a total of 349 CAMB individuals were registered with either a diagnosis (n = 337) or had died (n = 12) from ischemic heart disease before the end of follow-up (31 December 2017). The hazard ratios of ischemic heart disease according to satisfaction with life and vitality scores were investigated using Cox proportional hazard regression adjusted for potential covariates. Results. A one standard deviation increase on the SWLS was associated with an 18% reduced risk of ischemic heart disease while a one standard deviation increase on the SF-36 vitality scale was associated with a 24% reduced risk of ischemic heart disease after adjustment for baseline socio-demographic factors. These associations remained when separately adjusting for lifestyle, objective health, and social factors, but became non-significant when adjusting for self-reported health. Conclusion. Our study indicates that both psychological and health-related components of wellbeing are important in relation to ischemic heart disease.
