There are well-established theoretical and empirical foundations for a negative association between trait positive affectivity and anxiety symptoms in anxiety disorders and a positive association between trait negative affectivity and anxiety symptoms, respectively. However, no previous meta-analysis systematically estimated to what extent trait positive and negative affectivity are associated with anxiety symptoms in anxiety disorders. The aim of this study was to conduct a systematic review and meta-analysis to obtain an evidence-based estimate of the associations between trait positive and negative affectivity with anxiety symptoms in anxiety disorders.

Fifty years ago, the Rosenhan experiment was one of the most impactful psychological studies across decades. One of the main claims of the experiment was that clinicians could be negatively biased in their first clinical impressions, which would negatively impact further clinical decisions. We conducted two experiments ( = 56 and 64) in which psychotherapists were asked to give their first clinical impressions in two consecutive cases after a brief presentation of the case (case description and video excerpt) and a short recall task of the information provided.

Objectives: Cross-sectional studies suggest that individuals who perceive a broader future horizon may be more likely to consider the future consequences of their actions and, as a result, engage in healthy lifestyle behaviors. However, research has yet to consider how this association plays out on the daily level.

Methods: The present study used daily diary data from a sample of 198 older adults aged 60 years and older (M = 63.

Engagement in healthier lifestyle behaviors often is motivated by a focus on the future. However, there is limited research on the associations between health behavior and future time perspective, defined as people's tendency to perceive their future as expansive or as limited. Data came from a survey of U.

Background And Objective: Research has shown that perceptions of future time as limited are associated with more depressive symptoms. However, there is limited research on which dimensions of future time perspective (FTP: opportunity, extension, constraint) are associated with depression, anxiety, and stress, and whether these findings vary across age.

Design And Methods: Data came from a cross-sectional study in a nonclinical U.

Conscientiousness and sense of purpose consistently predict health, wellbeing, and health behavior. However, it remains an open question whether they are unique or overlapping predictors of health and wellbeing. The current study considered this question using the MOSAiCH study, a nationally representative sample of 2305 Swiss adults (: 52.

Longitudinal research is lacking with respect to how negative emotional reactivity and somatic symptoms during adolescence set the stage for later health. The aim of this longitudinal study was to examine within-person associations between negative emotional reactivity and somatic symptoms during adolescence and their effects on health and wellbeing in adulthood. Participants (N = 1527; 48.

Background: The aim of this study was to determine whether stimulation and support in early childhood and best friendship quality in adolescence predict adult personality.

Participants And Procedure: We used data from 123 individuals from an ongoing longitudinal study, with multiple assessment phases and modalities (observation, parental rating, self-report) to investigate prospective associations between stimulation and support in the home in early childhood (age 1-2), best friendship quality in adolescence (age 15), and the Big Five personality traits in adulthood (age 29) controlling for temperament, socioeconomic status (SES), and gender.

Results: After controlling for temperament, SES, and gender, we found that early childhood stimulation and support was related to adult openness to experiences, but not the other four traits, and that best friendship quality in adolescence was related to adult extraversion and agreeableness, but not conscientiousness, neuroticism, or openness to experiences.

Objective: Recent research suggests that personality traits can be changed by psychological interventions. However, it is unclear whether these intended personality changes can be maintained or merely reflect ephemeral shifts.

Method: The present study reports 1-year follow-up effects of a 3-month digital intervention for personality trait change.

Despite the value of sense of purpose during older adulthood, this construct often declines with age. With some older adults reconsidering the relevance of purpose later in life, the measurement of purpose may suffer from variance issues with age. The current study investigated whether sense of purpose functions similarly across ages and evaluated if the predictive power of purpose on mental, physical, cognitive, and financial outcomes changes when accounting for a less age-affected measurement structure.

The desire to change one's personality traits has been shown to be stronger if people are dissatisfied with associated aspects of their life. While evidence for the effects of interventions on personality trait change is increasing, it is unclear whether these lead to subsequent improvements in the satisfaction with various domains of life. In this study, we examined the effects of a 3-month digital-coaching personality change intervention study on 10 domains of satisfaction.

The goal of this study was to test the effects of a 7-week digital self-control intervention to increase physical activity using a two-arm randomized controlled trial. The self-control treatment group showed greater increases in self-reported physical activity (MET's) than the comparison group. Both groups significantly increased their daily steps and self-control.

Past research has suggested that the path to purpose involves connections with people along the way. In support, sense of purpose appears higher amongst those adults with more positive social relationships and interactions. However, research has yet to consider whether associations between sense of purpose and social relationship variables differ across adulthood.

Objective: Having a sense of purpose is associated with a wide variety of positive health outcomes, largely because purposeful individuals appear to take better care of themselves physically. However, work is limited regarding the role of purpose during health crises, such as the COVID-19 pandemic.

Method: The current cross-sectional study investigated whether having a sense of purpose was associated COVID-19 vaccination rates and willingness, among a Swiss adult sample (n = 2328, Mean = 52.

The current longitudinal study examined the predictive associations between the development of future perceptions in adolescence and depressive symptoms in adolescence and early and middle adulthood. Participants ( = 1,527; 48.3% female; broadly representative of Western Germany with respect to race/ethnicity and socioeconomic status) were measured yearly in adolescence at the age of 12 to 16 years and then in adulthood at the age of 35 and 45.

Objectives: There is limited information on how a change in patients' expectations over time results in symptom change in psychotherapy. This study aimed to investigate the changes in patients' expectations and symptoms during treatment and across follow-up as well as to determine the within- and between-patient relationships between two types of patient expectations, that is, self-efficacy and outcome expectation, and symptom change.

Methods: Participants (80 participants × 6 repeated measures; 480 observations) with generalized anxiety disorder were treated using cognitive behavioral therapy and the within- and between-patient scores of self-efficacy and outcome expectation were evaluated in multilevel models as predictors of symptom change.

Background: The working alliance refers to an important relationship quality between health professionals and clients that robustly links to treatment success. Recent research shows that clients can develop an affective bond with chatbots. However, few research studies have investigated whether this perceived relationship is affected by the social roles of differing closeness a chatbot can impersonate and by allowing users to choose the social role of a chatbot.

The present study examined associations between two future time perspective (FTP) dimensions (perceived opportunities and perceived time) and the Big Five personality traits during older adulthood, a developmental period that has received limited attention in personality development. Specifically, it tested whether FTP dimensions were cross-sectionally associated with personality traits, as well as if they predicted changes on those traits during a time when participants were transitioning to retirement. Participants from the Health, Ageing and Retirement Transitions in Sweden (HEARTS) study (N = 5,913, M = 63.

Worry is a central feature of generalized anxiety disorder (GAD). Although worry is related to anxiety and maintained by beliefs that worry is uncontrollable, there is scarce research on how individuals with GAD react to worry episodes in their daily life and how their positive experiences might impact reactions to worry episodes. The current study examined the level and variability of anxiety and controllability during high worry periods and positive experiences in GAD.
