The positivity scale

Five studies document the validity of a new 8-item scale designed to measure positivity, defined as the tendency to view life and experiences with a positive outlook. In the first study (N = 372), the psychometric properties of Positivity Scale (P Scale) were examined in accordance with classical test theory using a large number of college participants. In Study 2, the unidimensionality of the P Scale was corroborated with confirmatory factor analysis in 2 independent samples (N1 = 322; N2 = 457). In Study 3, P Scale invariance across sexes and its relations with self-esteem, life satisfaction, optimism, positive negative affect, depression, and the Big Five provided further evidence of the internal and construct validity of the new measure in a large community sample (N = 3,589). In Study 4, test-retest reliability of the P Scale was found in a sample of college students (N = 262) who were readministered the scale after 5 weeks. In Study 5, measurement invariance and construct validity of P Scale were further supported across samples in different countries and cultures, including Italy (N = 689), the United States (N = 1,187), Japan (N = 281), and Spain (N = 302). Psychometric findings across diverse cultural context attest to the robustness of the P Scale and to positivity as a basic disposition.

On the Cross‐Cultural Replicability of the Resilient,Undercontrolled, and Overcontrolled Personality Types

Personality types reflect typical configurations of personality attributes within individuals. Over the last 20 years, researchers have identified a set of three replicable personality types: resilient (R), undercontrolled (U), and overcontrolled (O) types. In this study, we examined the cross‐cultural replicability of the RUO types in Italy, Poland, Spain, and the United States. Personality types were identified using cluster analyses of Big Five profiles in large samples of college students from Italy (n = 322), the United States (n = 499), Spain (n = 420), and Poland (n = 235). Prior to clustering the profiles, the measurement invariance of the Big Five measure across samples was tested. We found evidence for the RUO types in all four samples. The three‐cluster solution showed a better fit over alternative solutions and had a relatively high degree of cross‐cultural generalizability. The RUO types are evident in samples from four countries with distinct linguistic and cultural traditions. Results were discussed in light of the importance of considering how traits are organized within individuals for advancing contemporary personality psychology.     

Family crisis intervention in war contexts: a case study of a traumatised Palestinian family

The aim of this study was to analyse the phases of an innovative in vivo exposure intervention in which all family members were present at the scene of a traumatic incident. Clinical practice has borne out the efficacy of family intervention and its benefits for traumatised individuals and family groups. The intervention discussed here was conducted with a Palestinian family that had suffered trauma in a missile attack during the Israeli–Lebanese war of summer 2006. Narrative and meaning-reconstruction methods were combined with cognitive-behavioural techniques. The study highlights the limitations of the intervention as well as suggesting future directions for integrated models of crisis intervention; development of an evidence-based model is recommended.     

A harbor seal can transfer the same/different concept to new stimulus dimensions

We investigated the formation of an abstract concept of same/different in a harbor seal by means of a two-item same/different task. Stimuli were presented on a TFT monitor. The subject was trained to respond according to whether two horizontally aligned white shapes presented on a black background were the same, or different from each other, by giving a no-go or go response. Training comprised of four stages. First, the same/different task was trained with two shapes forming two same problems (A–A and B–B) and two different problems (A–B and B–A). After the learning criterion was reached, training proceeded with new pairs of shapes. In the second experimental stage, every problem was presented just five times before new problems were introduced. We showed that training to criterion with just two shapes resulted in item-specific learning, whereas reducing the number of presentations to five per problem led to the formation of a same/different learning set as well as some restricted relational learning. Training with trial-unique problems in the third stage of this study resulted in the formation of an abstract concept of same/different which was indicated by a highly significant performance in transfer tests with 120 novel problems. Finally, extra-dimensional transfer of the concept was tested. The harbor seal showed a significantly correct performance on transfer tests with 30 unfamiliar pattern and 60 unfamiliar brightness same/different problems, thus demonstrating that the concept is not restricted to the shape dimension originally learned, but can be generalized across stimulus dimensions.     

Mood state,task demand,and effort-related cardiovascular response

Drawing on the mood-behaviour model (Gendolla, 2000), two studies investigated informational effects of mood on effort-related cardiovascular response. Experiment 1 manipulated mood state (positive, negative) and task difficulty (easy, difficult, extremely difficult). Effects on cardiovascular reactivity were as expected: On the easy level, reactivity was weak in a positive mood, but strong in a negative mood; on the difficult level, reactivity was strong in a positive mood, but weak in a negative mood; on the extremely difficulty level mood had no effect. Experiment 2 manipulated mood only. As predicted, subjective demand and cardiovascular response were both higher in a negative mood than in a positive mood and the mood effect on cardiovascular response diminished after statistically controlling for the demand appraisals. Neither study revealed any mood effects on cardiovascular response during the mood inductions.     

Is overgeneral autobiographical memory an isolated memory phenomenon in major depression?

The present study explored the relation between overgeneral autobiographical memory (AM) and other aspects of memory functioning in depression. A total of 26 patients with major depressive disorder completed a set of memory tasks measuring AM specificity (AMT; Williams & Broadbent, 1986), working memory, semantic memory, verbal learning, delayed verbal recall, recognition memory, and source memory. Reduced specificity of AM was related to poor working memory (central executive functioning) and poor source memory. The former finding conforms to the idea that the voluntary retrieval of specific autobiographical memories (AMs) involves central executive processes (e.g., Conway & Pleydell-Pearce, 2000 Conway, M. A. and Pleydell-Pearce, C. W. 2000. The construction of autobiographical memories in the self-memory system. Psychological Review, 107: 261–288. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). The latter finding replicates and extends recent findings suggesting that overgeneral AM is part of a broader memory deficit in retrieving the specific details of the context in which information was acquired (Ramponi, Barnard, & Nimmo-Smith, 2004 Raes , F. , Hermans , D. , Williams , J. M. G. , Demyttenaere , K. , Sabbe , B. , Pieters , G . & Eelen , P. ( 2004 ). Reduced specificity of autobiographical memory: A mediator between rumination and ineffective social problem solving in major depression? Journal of affective disorders , 87 , 331 – 335  [Google Scholar]). Furthermore, in line with Ramponi et al. (2004 Raes , F. , Hermans , D. , Williams , J. M. G. , Demyttenaere , K. , Sabbe , B. , Pieters , G . & Eelen , P. ( 2004 ). Reduced specificity of autobiographical memory: A mediator between rumination and ineffective social problem solving in major depression? Journal of affective disorders , 87 , 331 – 335  [Google Scholar]), rumination was found to be related to both overgeneral AM and poor source memory.     

Don't derogate this message! Self-affirmation promotes online type 2 diabetes risk test taking

The aim of the present study was to examine whether self-affirmation promotes acceptance of threatening type 2 diabetes information and risk-testing behaviour. In an experimental study (N = 84), we manipulated self-affirmation by allowing participants to affirm a value that was either personally important or unimportant to them, and measured participants' risk level prior to reading threatening type 2 diabetes information. As dependent variables, we measured message derogation, intentions to do an online type 2 diabetes risk test and online risk-testing behaviour. Findings showed that self-affirmation decreased message derogation, increased intentions to do an online risk test and promoted online risk test taking among at-risk participants. Among participants not at-risk, self-affirmation decreased intentions and online risk test taking. Therefore, it is concluded, that for an at-risk population self-affirmation can decrease defensive responses to threatening health information and promote (online) risk test taking for diseases.     

Emotional Stability and Affective Self‐regulatory Efficacy Beliefs: Proofs of Integration between Trait Theory and Social Cognitive Theory

The present study aimed to investigate the development and interplay of emotional stability and affective self‐regulatory efficacy beliefs through adolescence to young adulthood. A latent growth curve approach was used to investigate level and stability of emotional stability and self‐efficacy in managing negative emotions and in expressing positive emotions. We found that initial levels of emotional stability and self‐efficacy beliefs are highly correlated. In accordance with the posited hypothesis, the growth rate of perceived self‐efficacy in managing negative emotions predicted the growth rate of emotional stability, whereas the opposite path was not significant. The growth rates of perceived self‐efficacy in expressing positive emotions and emotional stability were not related to each other. Taken together, these findings point to self‐efficacy beliefs as instrumental to the change of traits. Practical implications of results are discussed, highlighting the role of social cognitive theory in supplying the proper strategies to design effective interventions to enable people to make the best use of their potentials.

A Longitudinal Investigation of Egoistic and Moralistic Self-Enhancement

This study used a 3-wave longitudinal design to investigate stability and change of egoistic and moralistic self-enhancement. Participants (n = 195) were followed for 6 years, from late adolescence (age 15) to emerging adulthood (age 21). A significant degree of rank-order stability was found that reveals a reasonable continuity in the individuals’ relative standing on measures of egoistic and moralistic self-enhancement. Latent growth curve analysis was used to track the developmental trajectories of the examined constructs. Findings revealed that egoistic self-enhancement is stable from 15 to 21 years, whereas moralistic self-enhancement slightly decreases during the same developmental period. Cross-lagged models were used to examine the reciprocal relations between self-enhancement and the Big Five personality traits. No prospective effects were found between the constructs, which develop independently from late adolescence to young adulthood, showing only synchronous associations. Implications for personality research and assessment are discussed.
