The reward and punishment responsivity and motivation questionnaire (RPRM-Q): A stimulus-independent self-report measure of reward and punishment sensitivity that differentiates between responsivity and motivation

Delving into the role of reward and punishment sensitivity in anorexia nervosa: Punishment responsivity as the only predictor of eating disorder symptom persistence in adolescents

OBJECTIVE

This study differentiated between self-reported punishment responsivity (PR) and motivation to avoid punishment (MP) and examined their relationship with anorexia nervosa (AN) and its course in a combined cross-sectional and longitudinal approach. We explored whether inconsistent findings regarding reward sensitivity may be explained by previous research not differentiating between reward responsivity (RR) and motivation to approach reward (MR).

METHOD

Participants were 69 adolescents with AN and 69 adolescents without AN matched on age, sex and educational level. Eating disorder (ED) symptom severity, PR, MP, RR, and MR were assessed at the start of treatment and 1 year later.

RESULTS

Only PR was higher in patients with AN than in the comparison group. Both PR and MP decreased over the course of 1 year, however, only the reduction in PR was related to the reduction in ED symptoms. Lastly, only higher baseline PR was independently related to less improvement in ED symptoms over the course of 1 year.

CONCLUSION

There was no support for the involvement of RS or its specific dimensions in AN. Most critical, the findings suggest that specifically the PR dimension of punishment sensitivity is related to the persistence of AN and could be an important target for treatment.

Explaining the causes and motivations for multiple substance use from the perspectives of users and therapists: A qualitative study

Background

The high prevalence of multiple substance use (MSU) is concerning, given the weak awareness about this issue and the potential impact this unawareness has on the severity of substance use disorder (SUD) and treatment outcomes. The aim of this study is to identify and elucidate the causes and motivations for MSU from the viewpoints of users and therapists in this field.

Methods

In this qualitative study, the conventional content analysis approach and purposive sampling were utilized. Deep semi-structured exploratory interviews were conducted with 17 substance users and 8 addiction therapists (including 4 psychiatrists, 3 general practitioners, and 1 psychologist). Field notes were also taken to identify and explain the motivations and reasons for MSU from the perspectives of users and therapists. The data were analyzed comparatively and simultaneously using the method suggested by Graneheim and Lundman (2004).

Results

Based on the findings of this study, the motivations for MSU are reflected in four main categories: 'Pharmacological factors' with subcategories such as achieving desired states and mitigating the undesirable effects of substances through leveraging the balancing, synergistic, and antagonistic effects of substances, substituting the effects of other substances, self-medication of the undesirable effects of other substances, enhancing the overall consumption experience such as heightened peak experience and enhanced pleasure, moderating the come-down, and seeking euphoria experiences in different substances; 'Biological factors' with subcategories including different neurobehavioral systems, individual differences determining substance dependence and the somatic-neural vulnerability of consumers; 'Psychosocial factors' with the subcategories of undesirable norms like the need for acceptance and social interactions, the context of substance use, consumers' experiences and expectations of substance use, and the maladaptive personality traits of consumers; and 'Addiction's inevitability' with the subcategories of coercion and the need to maintain equilibrium, and the difficulties of substance detoxification.

Conclusion

The motivations behind Multiple Substance Use (MSU) behaviors are multifaceted, including pharmacological, biological, psychosocial, and addiction-related factors. Recognizing and comprehending the interplay between these factors and motivations can inform better prevention strategies, assessment of treatment needs, and enhancement of treatment outcomes for individuals dealing with MSU.

Relationships between experimental task and questionnaire measures of reward/punishment sensitivity in attention-deficit/hyperactivity disorder (ADHD): protocol for a scoping review

INTRODUCTION

One of the purported underlying causal mechanisms of attention deficit hyperactivity disorder (ADHD) is altered motivational processes. Questionnaires have been used to identify the characteristics of reward and punishment sensitivity in individuals with ADHD. However, these questionnaires were initially developed to measure individual traits related to anxiety (inhibitory) and impulsivity (approach) tendencies or differences in pleasure-seeking. These reward and punishment sensitivity questionnaires are useful but might not capture all relevant aspects of altered motivational processes in ADHD. The proposed scoping review aims to: (1) examine which aspects of hypothesised altered reward and punishment sensitivity correspond to constructs measured by existing questionnaires, (2) characterise the relationships between ADHD symptomatology and reward and punishment sensitivity as measured by existing questionnaires and (3) evaluate the consistency between the altered reward and punishment sensitivity as measured by existing questionnaires and experimental task performance.

METHODS AND ANALYSIS

Reporting of the scoping review results will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews and the Joanna Briggs Methodology for Scoping Reviews. Published English-language literature was searched in three electronic databases (PubMed, Web of Science, APA PsycINFO) on 16 November 2023, with no restriction on the year of publication. Two researchers independently screened all identified titles/abstracts before proceeding to full-text review and additional handsearching of relevant studies. A narrative review and conclusions will be presented together with tables summarising the articles reviewed and the results organised by the three aims.

ETHICS AND DISSEMINATION

This study reviews existing publications with ethical approval in place. Therefore, ethical approval is not required. Review results will be disseminated through academic conferences and peer-reviewed manuscripts. Scoping review results will also inform future research to measure and identify altered motivational processes in ADHD.

Adaptive and maladaptive emotion regulation skills are associated with food intake following a hunger-induced increase in negative emotions

Many individuals would like to lose weight and often attempt to do so by dieting. However, dieting attempts often backfire and contribute to the risk of weight gain and obesity. Food restriction inevitably leads to hunger and hunger, in turn, induces negative emotions. The inability to regulate such a hunger-induced increase in negative emotions in an adaptive way may be responsible for overeating. The current study aimed to gain a better understanding of this potential psychological mechanism underlying failed dieting attempts. Adaptive and maladaptive emotion regulation (ER) were assessed with an online questionnaire in women with a healthy weight. Subsequently, participants were assigned to the fasted condition (fasting for 14h, n = 49) or the satiated condition (eating between 2 h and 30 min before the lab session, n = 59) and attended a lab session in which they completed tasks while given the opportunity to eat chips and M&M's. We did not find an association between any ER variable and the likelihood to begin eating. Among those who began eating, higher scores on adaptive cognitive ER and on maladaptive behavioral ER were associated with lower caloric intake in fasted individuals. Higher scores on adaptive behavioral ER were associated with higher caloric intake in fasted individuals. Utilizing adaptive cognitive ER when experiencing a hunger-induced increase in negative emotions may help individuals manage their food intake and maintain a healthy weight.
