Cutoff scores for the 8-item version of the Chronic Pain Acceptance Questionnaire (CPAQ-8) to identify different profiles of pain acceptance patterns, levels of function and behavioral flexibility

Examining a brief measure and observed cutoff scores to identify reward and relief drinking profiles: Psychometric properties and pharmacotherapy response

BACKGROUND

Precision medicine approaches attempt to reduce variability in alcohol use disorder (AUD) outcomes by identifying patient characteristics that predict response to a particular treatment. Recent work has examined the extent to which individuals with AUD may seek alcohol to enhance positive experiences (reward drinking) or relieve negative states (relief drinking) and shown that a high reward/low relief phenotype predicts naltrexone treatment response. Yet, limitations of reward/relief drinking measures may hamper efforts to translate findings to clinical practice. We sought to refine a brief measure of reward/relief drinking and develop cutoff scores to identify reward/relief subgroups that predict pharmacotherapy response.

METHODS

The Inventory of Drinking Situations (IDS), used in previous studies to measure reward/relief drinking, was administered to 426 participants (77% male; average age = 45.3) in a clinical trial examining naltrexone and acamprosate.

RESULTS

Item response theory and tests of differential item functioning across sex, age, and alcohol dependence severity were used to create a 10-item measure, titled the Reward and Relief IDS (RR-IDS). Cutoff scores on the RR-IDS for the reward/relief drinking subgroups were identified using latent profile and area under the curve analyses. The cutoff scores demonstrated good construct validity. Individuals in the high reward/low relief subgroup who received naltrexone or acamprosate had a decreased likelihood of heavy drinking (large effect sizes) versus those who received placebo.

CONCLUSIONS

The RR-IDS is a practical measure for identifying reward/relief subgroups and predicting pharmacotherapy response. Pending replication of these findings, the RR-IDS could be a critical precision medicine tool for prescribing AUD medications.

The association between work-related physical and psychosocial factors and musculoskeletal disorders in healthcare workers: Moderating role of fear of movement

Objectives

Knowledge is lacking on the interaction between fear of movement (FOM) and work‐related physical and psychosocial factors in the development and persistence of musculoskeletal disorders (MSDs).

Methods

In this cross‐sectional study, 305 healthcare workers from several Belgian hospitals filled out a questionnaire including sociodemographic factors, work‐related factors (social support, autonomy at work, workload, and physical job demands), FOM, and MSDs for different body regions during the past year. Path analysis was performed to investigate (1) the association between the work‐related factors, FOM and MSDs, and (2) the moderating role of FOM on the association between the work‐related factors and MSDs among healthcare workers.

Results

Complaints were most frequently located at the neck–shoulder region (79.5%) and lower back (72.4%). Physical job demands (odds ratio [OR] 2.38 and 95% confidence interval [CI] 1.52–3.74), autonomy at work (OR 1.64 CI [1.07–2.49]) and FOM (OR 1.07 CI [1.01–1.14] and OR 1.12 CI [1.06–1.19]) were positively associated with MSDs. Healthcare workers who experienced high social support at work (OR 0.61 CI [0.39–0.94]) were less likely to have MSDs. Fear of movement interacted negatively with workload (OR 0.92 CI [0.87–0.97]) and autonomy at work (OR 0.94 CI [0.88–1.00]) on MSDs.

Conclusions

Work‐related physical and psychosocial factors as well as FOM are related to MSDs in healthcare workers. FOM is an important moderator of this relationship and should be assessed in healthcare workers in addition to work‐related physical and psychosocial factors to prevent or address MSDs.

Catastrophising, pain self-efficacy and acceptance in patients with Burning Mouth Syndrome

BACKGROUND

Little is known about pain catastrophising, pain self-efficacy and chronic pain acceptance in burning mouth syndrome (BMS) and their effect on health-related quality of life (HRQoL) and symptoms of anxiety and depressive disorders.

OBJECTIVES

To describe pain catastrophising, pain self-efficacy and pain acceptance in BMS patients and explore associations with affective function and HRQoL.

METHODS

A cross-sectional study of 36 BMS patients (31 female) referred to an Orofacial Pain Clinic completed the Pain Catastrophizing Scale, the Pain Self-Efficacy Questionnaire and the Chronic Pain Acceptance Questionnaire-8 in addition to standardised self-reported questionnaires measuring mood and oral and generic HRQoL.

RESULTS

Pain catastrophising levels were markedly higher than (non-clinical) population norms, with 32.0% of patients reporting clinically relevant levels. Pain self-efficacy and chronic pain acceptance varied widely; 24.0% evidenced low confidence to cope with pain, and 53.8% reported low activity engagement and/or low pain willingness. Catastrophising showed moderate-to-strong associations with measures of anxiety (r = 0.63), depression (r = 0.80), and oral (r = 0.61) and generic HRQoL (rho=-0.84). Self-efficacy and acceptance were also closely related to levels of depression (r/rho=-0.83 to -0.73) and generic HRQoL (r/rho = 0.74 to 0.75). These associations were stronger than those between pain severity and affective function/HRQoL and persisted after controlling for pain severity.

CONCLUSIONS

A substantial proportion of BMS patients evidence maladaptive beliefs about personal effectiveness in managing pain, which is closely related to affective disorders and impaired HRQoL. As such, treatment approaches targeting catastrophising, pain self-efficacy and acceptance may prove beneficial in improving mood and quality of life in BMS patients.
