General practitioner advance care planning knowledge and attitudes: ACP-GP cluster-randomised controlled trial.

OBJECTIVES: Advance care planning (ACP) supports adults understanding and sharing their values, goals, and preferences regarding future medical care. General practitioners (GPs) are key figures in conducting ACP conversations with patients. GPs' ACP knowledge and attitudes have been identified as potential barriers. This study evaluates the effects of ACP-GP, a complex ACP intervention, on GPs' knowledge and attitudes. METHODS: A phase-III cluster-randomised controlled trial. 35 Belgian GPs participated. The intervention included a training for GPs, ACP conversations, a patient workbook, and a documentation template. GPs' knowledge and attitudes were assessed using an adaptation of the Next Steps questionnaire, at baseline, three, and six months postintervention. Generalised estimating equations were applied to analyse the data. RESULTS: Analyses showed no intervention effect on GPs' knowledge (W(2)=4.18, p=.123) and attitudes (all W(2)<3.85, all p>.146) compared with the control group. CONCLUSIONS: The ACP-GP intervention did not improve GPs' knowledge and attitudes. Failure to detect an effect may stem from a ceiling effect, with GPs scoring high on baseline outcomes across groups. Questionnaires may require fine-tuning to accurately map their suggested role as potential barriers. TRIAL REGISTRATION NUMBER: Prospectively registered at ISRCTN (ISRCTN12995230) on 19 June 2020.

Youth baseline and state pain-related injustice appraisals are associated with emotional responses of anger and sadness: An experimental study.

Background: Youth pain-related injustice appraisals are associated with adverse functioning; however, mechanisms by which injustice appraisals exert their impact have yet to be elucidated. Adult injustice literature suggests anger, sadness, and attention bias to anger (AB) as potential mechanisms. This study examined the effects of injustice appraisals in a healthy youth sample by applying a justice violation manipulation. We hypothesized the justice violation condition to lead to worse pain outcomes with effects mediated by anger, sadness, and AB as compared to the control condition. We further explored associations between both baseline and state injustice appraisals and anger, sadness, and AB across conditions. Methods: A 2 × 2 time by condition design was used to test hypotheses. 133 healthy youth aged 9-16 years old completed two cold pressor tasks (CPTs). In the experimental (i.e., justice violation) group, participants were initially told to complete one CPT, but were told afterwards to perform it again due to experimenter negligence. In the control group, no justice violation occurred. Baseline injustice appraisals and pain catastrophizing were assessed with the Injustice Experience Questionnaire and Pain Catastrophizing Scale for Children; state outcomes (i.e., injustice, catastrophizing, anger, sadness) were assessed after CPTs. AB was indexed using a dot-probe task. Results: Findings indicated no effects of the justice violation on pain outcomes or associated mechanisms, nor on injustice appraisals, suggesting manipulation failure. However, across conditions, baseline and state injustice appraisals were positively associated with anger and sadness, but not with AB. Conclusions: Despite the experimental justice violation failing to elicit differential injustice appraisals across conditions, the current study supports both anger and sadness as key emotional responses associated with pain-related injustice appraisals in a healthy youth sample.

Child pain-related injustice appraisals mediate the relationship between just-world beliefs and pain-related functioning.

BACKGROUND: Research among adult and paediatric samples suggests that pain-related injustice appraisals contribute to adverse pain-related functioning. However, a singular focus on pain-related injustice appraisals carries the risk of underestimating the role of broader concepts of justice. This study examined the unique roles of child pain-related injustice appraisals and just-world beliefs in understanding disability and physical, emotional, social and academic functioning, as well as the mediating role of injustice appraisals in the relationship between just-world beliefs and functioning. METHODS: Participants comprised a school sample of 2,174 children (Study 1) and a clinical sample of 146 paediatric chronic pain patients (Study 2) who completed the Injustice Experience Questionnaire (IEQ), Personal and General Belief in a Just World scales (JWB-P/G), Functional Disability Inventory (FDI), Pain Catastrophizing Scale for Children (PCS-C) and Pediatric Quality of Life Inventory (PEDSQL). RESULTS: For both samples, child pain-related injustice appraisals were associated with poorer functioning, after controlling for just-world beliefs, catastrophizing, pain intensity, age and sex. In the school sample, injustice appraisals mediated the associations of both personal and general just-world beliefs with functioning. In the clinical sample, injustice appraisals mediated the association of personal, but not general, just-world beliefs with all functioning scales. CONCLUSIONS: The current findings attest to the unique role of pain-related injustice appraisals in understanding child pain-related functioning and their explanatory value in understanding the relationship between fundamental just-world beliefs and child pain-related functioning. SIGNIFICANCE: The present study adds to emerging literature on the adverse effects of child pain-related injustice appraisals in the context of pain, through showing that pain-related injustice appraisals are uniquely associated with pain-related functioning and mediate the relationship between just-world beliefs and pain-related functioning. These findings suggest that interventions may target pain-related injustice appraisals as a mechanism for change in children.
