The SFS showed some degree of ecological validity at assessing broad aspects of social functioning. Low scores on the SFS social engagement/withdrawal and interpersonal behaviour dimensions captured social isolation and social avoidance in daily life, but not lack of interest in socializing. Ecological validity of the SFS activity domain was low. ESM offers a rich alternative to classical assessment techniques of social functioning.

The relationship between companion animal ownership and wellbeing has received an increasing amount of scientific attention over the last few decades. Although the general assumption is that individuals benefit from the presence of companion animals (termed the "pet-effect"), recent evidence suggests that the nature of this association is diverse and complex and that many of the studies performed so far are subject to methodological constraints. This study therefore aimed to investigate the pet-effect in the natural setting of pet-owners' daily life. Using the Experience Sampling Method (a signal contingent ecological assessment technique), 55 dog or cat owners reported for five consecutive days, at ten random time-points each day, in the moment whether a pet was present and to what extent they interacted with it. In addition, at each measurement moment they reported on their current positive and negative affect, using 11 mood-related adjectives derived from the Positive And Negative Affect Schedule (PANAS). Multilevel regression analyses showed that negative affect was relatively lower at moments when the companion animal was present (vs. absent) (B = -0.09, p = 0.02, 95%CI = -0.16; -0.02). In addition, the level of interaction with a companion animal was positively associated with positive affect (B = 0.04, p < 0.001, 95%CI = 0.01; 0.07). These results are in line with the pet-effect hypothesis in suggesting that the presence of and interaction with companion animals is associated with aspects of emotional wellbeing. More specifically, the presence of a companion animal may buffer against negative feelings, while interacting with a companion animal may generate positive feelings. This differential effect on positive versus negative affect also shows that the pet-effect is not an unequivocal effect. Different aspects of the human-animal relationship may influence different aspects of wellbeing.

Social functioning, when assessed in an ecologically valid fashion, is not sensitive to variation in the traditional experimental assessment of emotion recognition. Real life measures of functioning should guide research linking the handicaps associated with psychosis to underlying cognitive and emotional dysregulation.

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.

BackgroundIn order to assess the importance of environmental and genetic risk on transition from health to psychotic disorder, a prospective study of individuals at average (n = 462) and high genetic risk (n = 810) was conducted.MethodA three-year cohort study examined the rate of transition to psychotic disorder. Binary measures indexing environmental exposure (combining urban birth, cannabis use, ethnicity and childhood trauma) and proxy genetic risk (high-risk sibling status) were used to model transition.ResultsThe majority of high-risk siblings (68%) and healthy comparison subjects (60%) had been exposed to one or more environmental risks. The risk of transition in siblings (n = 9, 1.1%) was higher than the risk in healthy comparison subjects (n = 2, 0.4%; ORadj  = 2.2,95%CI:5–10.3). All transitions (100%) were associated with environmental exposure, compared to 65% of non-transitions (p = 0.014), with the greatest effects for childhood trauma (ORadj  = 34.4,95%CI:4.4–267.4), cannabis use (OR = 4.1,95%CI:1.1, 15.4), minority ethnic group (OR = 3.8,95%CI:1.2,12.8) and urban birth (OR = 3.7,95%CI:0.9,15.4). The proportion of transitions in the population attributable to environmental and genetic risk ranged from 28% for minority ethnic group, 45% for urban birth, 57% for cannabis use, 86% for childhood trauma, and 50% for high-risk sibling status. Nine out of 11 transitions (82%) were exposed to both genetic and environmental risk, compared to only 43% of non-transitions (p = 0.03).ConclusionEnvironmental risk associated with transition to psychotic disorder is semi-ubiquitous regardless of genetic high risk status. Careful prospective documentation suggests most transitions can be attributed to powerful environmental effects that become detectable when analysed against elevated background genetic risk, indicating gene-environment interaction.

A balanced time perspective can help retaining or improving happiness. Research shows shifts in time perspective while ageing. In order to reach a better understanding of the value of time perspective in different age groups, results are reported of a survey (n = 525), which examines the moderating role of age in the association between time perspective and happiness. Time perspective was measured by the Zimbardo Time Perspective Inventory (ZTPI) (Zimbardo and Boyd in J Personal Soc Psychol 77: [1271][1272][1273][1274][1275][1276][1277][1278][1279][1280][1281][1282][1283][1284][1285][1286][1287][1288] 1999) and to measure happiness, the Subjective Happiness Scale of Lyubomirsky and Lepper (Soc Indic Res 46:137-155, 1999) was used. Regression analysis shows that time perspective is indeed associated with happiness and that, although the assumed shifts in time perspective over time were not found, age does act as a moderator of this association. With ageing, the negative association between a past-negative time perspective and happiness weakens. These results add to our understanding of the theoretical concept of time perspective and shed new light on the value of a balanced time perspective for someone's wellbeing. Theoretical and practical implications of these findings are discussed.
