How do you know you know that you're doing ACT?” An experimental study of simulated therapy sessions to explore the measurement properties of the Acceptance and Commitment Therapy Fidelity Measure (AC…
The Acceptance and Commitment Therapy-Fidelity Measure (ACT-FM) offers a user-friendly assessment of ACT delivery in clinical trials and clinical practice. However, the ACT-FM's measurement properties have not been adequately explored. This study tests whether it performs two key functions: 1) discriminates between therapy sessions delivered with different levels of fidelity to ACT principles; 2) enables reliable scoring. In total, 14 clinicians …
Correlates and Predictors of Symptom Severity Over Time in People Under Investigation for Postural Orthostatic Tachycardia Syndrome
OBJECTIVE: Postural orthostatic tachycardia syndrome (POTS) is a poorly understood chronic disorder characterized by an unexplained excessive increase in heartbeat upon standing. The aim of this study was to investigate psychosocial and physiological correlates and predictors of symptom severity over time in patients presenting with POTS-like symptoms. METHODS: Longitudinal cohort study of patients under investigation for POTS ( n = 149). Patient…
Adolescent Sexual Behavior Patterns in a British Birth Cohort
This study examined adolescent sexual behaviors patterns, and the consistency between sexual behavior and sexual orientation, in a prospective birth cohort. We used data on 5150 young people from the Avon Longitudinal Study of Parents and Children. Sexual orientation was assessed using a 5-point scale of sexual attraction at 15.5 years. Fourteen sexual activities were assessed using the Adolescent Sexual Activities Index at 13.5 and 15.5 years. L…
Infant feeding practices among macrosomic infants
The health benefits of breastfeeding are well recognised, but breastfeeding rates worldwide remain suboptimal. Breastfeeding outcomes have yet to be explored among women who give birth to macrosomic (birthweight ≥4000 g) infants, a cohort for whom the benefits of breastfeeding may be particularly valuable, offering protection against later-life morbidity associated with macrosomia. This longitudinal prospective cohort study aimed to identify whet…
Adolescent Sexual Behavior Patterns, Mental Health, and Early Life Adversities in a British Birth Cohort
This study tested adolescent sexual behavior patterns at age 14, their association with mental health at age 17 (psychological well-being, substance use, and self-harm attempts), and the influence of early life adversities upon this association. A British birth cohort (5,593 boys and 5,724 girls from the Millennium Cohort Study) was used. Latent class analysis suggested five subgroups of adolescent sexual behaviors: a "no sexual behavior" (50.74%…
Childhood gender nonconformity and the stability of self-reported sexual orientation from adolescence to young adulthood in a birth cohort
This study quantified changes in self-reported sexual orientation from adolescence to early adulthood, and whether childhood gender nonconformity (GNC) predicted sexual orientation changes. Youth (2,678 boys and 3,359 girls; 96.09% ethnically White) from the Avon Longitudinal Study of Parents and Children (ALSPAC) were included. Self-reported sexual orientation was measured using sexual attraction (5-point scale) at ages 15.5, 21, and 23. GNC was…
Childhood Maltreatment, Gender Nonconformity, and Adolescent Sexual Orientation
This study tested whether associations between childhood maltreatment and adolescent sexual orientation were accounted for by childhood gender nonconforming behavior (GNCB) in a prospective birth cohort (N = 5,007). Childhood parental maltreatment (physical and emotional) and GNCB were assessed on multiple occasions up to age 6 years, and sexual orientation at 15.5 years. Boys with a history of maltreatment were significantly more likely to be no…
The Role of Prediagnosis Audiovestibular Dysfunction Versus Distress, Illness-Related Cognitions, and Behaviors in Predicted Ongoing Dizziness Handicap
OBJECTIVE: People with chronic vestibular diseases experience variable degrees of self-perceived disability. However, longitudinal data examining the predictive validity of relevant clinical variables alongside psychological variables are limited. The present study examined whether these factors predict self-reported dizziness handicap 3 months after assessment and diagnosis. METHODS: Patients were recruited from a waiting list of a tertiary neur…
Sexual Orientation and Cognitive Ability
A cross-sex shift model of human sexual orientation differences predicts that homosexual men should perform or score in the direction of heterosexual women, and homosexual women in the direction of heterosexual men, in behavioral domains such as cognition and personality. In order to test whether homosexual men and women’s cognitive performance was closer to that of heterosexual men or that of heterosexual women (i.e., sex-atypical for their sex …
Early life conditions and adolescent sexual orientation
This study tested the association between multiple prenatal and postnatal early life factors and adolescent sexual orientation in a longitudinal birth cohort. Factors included birth weight, gestational age, parental age at birth, number of older brothers and sisters, breastfeeding, maternal anxiety/depression, family socioeconomic position, parent-child relationships, parental absences, pubertal body mass index, and housing issues. We used data o…
Stress, Illness Perceptions, Behaviors, and Healing in Venous Leg Ulcers
OBJECTIVE: The aim of the study was to investigate the impact of stress, illness perceptions, and behaviors on healing of venous leg ulcers. METHODS: A prospective observational study of 63 individuals for 24 weeks investigated possible psychosocial predictors of healing. There were two indices of healing: rate of change in ulcer area and number of weeks to heal. Psychological variables were assessed at baseline using self-report measures (Percei…

Civil war peace agreement implementation and state capacity
Negotiated civil war terminations differ from their interstate war counterparts in that one side must disarm and cease to exist as a fighting entity. While termination through military victory provides a relatively more enduring peace, many civil wars end with peace agreements signed after negotiations. However, research has shown that the implementation of civil war peace agreements is difficult and prone to collapse. Often these failures are fo…
