Validity of a Revised Obsessive-Compulsive Personality Disorder (OCPD) Trait Profile and Its Relationship with Social Interaction Anxiety and Coping.

There is evidence suggesting that the conceptualization and operationalization of Obsessive-Compulsive Personality Disorder (OCPD) is not satisfactory (Watters et al., 2019). In this study, we used an online sample (N = 1008) to investigate the construct validity of the PID-5 OCPD trait measure. Regression analyses supported our hypothesis that rigid perfectionism captured the core phenomenology of OCPD whereas restricted affectivity and intimacy avoidance were not conceptually related to the OCPD construct. Based on the biosocial theory for overcontrol (Lynch, 2018), we introduced anxiousness and workaholism to the PID-5 OCPD trait profile. In establishing the validity of the revised OCPD trait profile, we investigated, for the first time, the role of social interaction anxiety and maladaptive coping in OCPD. Our revised OCPD profile showed good validity and was characterized by marked social interaction anxiety and dysfunctional coping mechanisms. The findings may lead to a new conceptualization of OCPD which prioritizes deficits in social interaction and coping. We identify areas that need to be prioritized in the evaluation of OCPD by mental health professionals and offer avenues for new clinical research in the field.

What techniques might be used to harness placebo effects in non-malignant pain? A literature review and survey to develop a taxonomy.

OBJECTIVES: Placebo effects can be clinically meaningful but are seldom fully exploited in clinical practice. This review aimed to facilitate translational research by producing a taxonomy of techniques that could augment placebo analgesia in clinical practice. DESIGN: Literature review and survey. METHODS: We systematically analysed methods which could plausibly be used to elicit placebo effects in 169 clinical and laboratory-based studies involving non-malignant pain, drawn from seven systematic reviews. In a validation exercise, we surveyed 33 leading placebo researchers (mean 12 years’ research experience, SD 9.8), who were asked to comment on and add to the draft taxonomy derived from the literature. RESULTS: The final taxonomy defines 30 procedures that may contribute to placebo effects in clinical and experimental research, proposes 60 possible clinical applications and classifies procedures into five domains: the patient’s characteristics and belief (5 procedures and 11 clinical applications), the practitioner’s characteristics and beliefs (2 procedures and 4 clinical applications), the healthcare setting (8 procedures and 13 clinical applications), treatment characteristics (8 procedures and 14 clinical applications) and the patientâ€"practitioner interaction (7 procedures and 18 clinical applications). CONCLUSION: The taxonomy provides a preliminary and novel tool with potential to guide translational research aiming to harness placebo effects for patient benefit in practice.

Descriptive and predictive validity of somatic attributions in patients with somatoform disorders: a systematic review of quantitative research.

OBJECTIVE: Research on hypochondriasis and other somatoform disorders (SFD) has provided evidence that patients with SFD tend to attribute their symptoms to organic dysfunctions or disease. However, recent studies appear to discredit this. There is no systematic evidence on whether patients with SFD predominantly rely on somatic attributions, despite calls to include somatic attributions as a positive criterion of somatic symptom disorder (SSD) in the upcoming Diagnostic and Statistical Manual of Mental Disorders (DSM-5). METHODS: This study is a systematic review of quantitative studies which assess the descriptive and predictive validity of somatic attribution in SFD. The literature search was restricted to studies with patients who met the DSM-IV criteria for SFD. RESULTS: Somatic attribution style in SFD has acceptable descriptive but insufficient predictive validity. This confirms that the overlap between somatic and psychological attributions is often substantial. Attribution style can discriminate between SFD patients with and without comorbidity. CONCLUSION: A somatic attribution style does not qualify as a positive criterion in SSD. However, there is an urgent need for further research on causal illness perceptions in the full spectrum of medically unexplained symptoms in order to confirm this result. Given its high prevalence, research on psychological attribution style is warranted. Re-attribution does not provide a framework sophisticated enough to address the needs of patients in primary care.

Relationship between price paid for off-trade alcohol, alcohol consumption and income in England: a cross-sectional survey.

AIMS: In order to examine the potential impact of an increase in the minimum price per unit of alcohol to 50 pence ($0.78), we examined drinking patterns and household incomes of people who purchase alcohol in England at above and below this price. METHODS: Cross-sectional survey of 515 members of the public in seven towns and cities in the south of England. The primary outcome was whether the participant had purchased alcohol at <50 p/unit. The main exposures were annual household income and alcohol consumption, measured using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C). RESULTS: The median price paid per unit of alcohol was 53.1 pence (range 16.4-297.0 pence). Those buying alcohol at <50 p/unit had a mean AUDIT-C score of 6.2 compared with 5.5 among those buying alcohol at above this price. The odds ratio (OR) of a person on low income with high-risk drinking purchasing alcohol at <50 p/unit was 1.29 [95% confidence interval (CI) = 0.82-1.79] compared with all other study participants. The OR of a person on low income with low-risk drinking purchasing alcohol below this price was 0.51 (95% CI = 0.30-0.87) compared with all other participants. CONCLUSIONS: These data suggest that an increase in the minimum price of alcohol to 50 pence price per unit is only likely to disproportionately affect people on low incomes if their alcohol consumption is excessive.
