The Relationship between Alcohol Hangover Severity, Sleep and Cognitive Performance; a Naturalistic Study

Alcohol hangover (AH) has been associated with poor sleep due to the negative effects of alcohol intoxication on sleep quantity and sleep quality. The aim of the current study was to further explore the relationship between AH severity and sleep using a naturalistic study design. A further aim was to determine whether quantitative aspects of sleep were a mediating influence on the relationship between AH severity and cognitive performance. As part of the naturalistic study design, 99 drinkers were recruited following a night of drinking in an Australian state capital, with breath alcohol concentration (BrAC) measured as participants were leaving the entertainment district. The following morning at home, participants answered online questions regarding their drinking behaviour on the previous evening, current AH symptoms and sleep quality. Participants also completed an online version of the Trail-Making Test B (TMT-B) to assess cognitive performance. The findings reveal the duration of nightly awakenings to be negatively related to six individual AH symptoms as well as overall AH severity. The number of nightly awakenings, sleep quality and total sleep time correlated with four AH symptoms including overall AH severity. Total AH severity accounted for a moderate amount of variance (11%) in the time to complete the TMT-B. These findings confirm that alcohol consumption negatively affects sleep, which is related to higher next-day hangover severity ratings and poorer cognitive performance.

The Effects of Collective Ritual on Affect, Unity, and Pro-Sociality: A Naturalistic Study

<p>Anthropologists have long speculated that collective group rituals endure due to their functional capacity to foster co-operation and cohesion within groups and thus help societies to overcome free-rider problems. Recently, experimental studies have provided empirical data to support this hypothesis and have suggested that synchronous group movement as a key element in this process. Further more, recent field studies have suggested that the sacred values surrounding rituals may mediate the synchrony/pro-sociality relationship. The current study aims to further explore the psychological affects of group ritual in terms of positive affect, perceptions of group unity, and pro-sociality in naturalistic settings. Additionally the current study extrapolates out physical arousal and religiosity as important elements of ritual as well as synchronous movement. Our results suggest that the psychological modulations of positive affect, perceived group unity, and pro-sociality in rituals are primarily due to the meaning context within which they are performed. Results have also shown that when used together in a religious context, rituals that use high levels of synchrony and physicality are associated with higher levels of positive affect and co-operation within groups. These findings may help to explain the expansion of charismatic religions in those regions of the world where there are lower levels of security. They also suggest that past laboratory studies of ritual have been limited due to their inability to assess the meaning contexts that may be driving the effects found. Further research is required to assess the rates of endurance of these psychological affects outside of ritualistic settings and also the generalisation of pro-sociality to outgroups. Also, future development of more accurate measures of variables for field use will provide additional strength and reliability within this field.</p>

The Impact of Clients’ and Therapists’ Characteristics on Therapeutic Alliance and Outcome

This article investigates distances between therapists and their clients in their experience of the therapeutic alliance across the duration of the psychotherapeutic treatments in a naturalistic study. We looked at the working alliances from different vantage points—rupture, repair of ruptures, distances in the alliance impressions of both clients and therapists—and their correlation with treatment outcome. The only predictive variable of alliance ruptures was the inability of therapists to bond sufficiently with their clients regarding a sustainable working atmosphere, which could be identified through a continuous distant alliance rating by the therapists. Alliance ruptures in turn significantly predicted premature termination of treatments, whereas alliance ruptures per se did not necessarily predict treatment outcome. The paper discusses the possible role of the quality of therapists’ attachment styles as a potentially crucial variable in an effective working alliance in psychotherapy.

Study protocol for a pilot high-intensity interval training intervention in inpatient mental health settings: a two-part study using a randomised controlled trial and naturalistic study design

Background Severe mental illnesses (SMI), including schizophrenia spectrum disorder, bipolar disorder and major depressive disorder, are associated with physical health comorbidities and premature mortality. Physical activity and structured exercise have a beneficial impact on cardiometabolic risk and ameliorate mental health symptomology and cognition. This protocol describes a feasibility study for a high-intensity interval training (HIIT) intervention among inpatients with SMI, to improve their physical and mental health. Methods The feasibility study follows a two-part design owing to COVID-19-related adaptations to project design: (a) a non-blinded randomised controlled trial (RCT) of 12 weeks of bicycle-based HIIT, delivered twice weekly in a face-to-face, one-to-one setting, compared to treatment as usual (TAU) and (b) a naturalistic study of inpatient HIIT; eligible participants will be invited to two sessions of HIIT per week, delivered by the research team remotely or in person. Additionally, participants in the naturalistic study may use the bike to conduct self-directed sessions of their chosen length and intensity. We will measure the feasibility and acceptability of the HIIT intervention as primary outcomes, alongside secondary and tertiary outcomes evaluating the physical, mental and cognitive effects of HIIT. The study aims to recruit 40 patients to the RCT and 6–8 patients to the naturalistic design. Discussion Exercise is a modifiable lifestyle barrier that can reverse cardiometabolic disease risk. If HIIT is found to be feasible and acceptable in inpatients with SMI, there would be scope for large-scale work to evaluate the clinical, cost and implementation effectiveness of HIIT in inpatient mental health settings.
