Reducing dropout in acceptance and commitment therapy, mindfulness-based cognitive therapy, and problem-solving therapy for chronic pain and cancer patients using motivational interviewing.

OBJECTIVE: Acceptance and commitment therapy, mindfulness-based cognitive therapy, and problem-solving therapy are types of cognitive-behavioural therapy (CBT) group that improve physical and mental health in chronic pain or cancer. However, dropout is high due to group demands alongside physical impairments. Motivational interviewing (MI) is a well-evidenced means of enhancing treatment adherence. Few studies have investigated MI as an adjunct to CBT in cancer or chronic pain, and none have established the minimum MI duration required for adherence improvement. This study evaluated minimal-duration MI to improve adherence in three CBT group types for cancer and chronic pain. METHODS: In a cohort study of 99 cancer and chronic pain patients, 47 were given a 10- to 15-min structured MI telephone intervention (MI-call) after the first session. The remaining 52 received a CBT group without MI (no-MI). RESULTS: Odds of completing group CBTs were five times greater for patients in the MI-call cohort versus no-MI. Effects remained when controlling for age, gender, diagnosis, group type, and baseline quality of life. The MI-call cohort attended one extra session per patient compared to no-MI, controlling for age, gender, and diagnosis. CONCLUSIONS: A brief MI telephone intervention may improve adherence to group CBTs in cancer and chronic pain. PRACTITIONER POINTS: A brief motivational interviewing (MI) telephone intervention may reduce dropout from group cognitive-behavioural therapies (CBTs) for cancer and chronic pain patients when administered after the first group session in routine care. Recipients of this intervention were five times more likely to complete a group CBT programme than those who did not receive it. Therefore, a minimal-dose MI intervention can have clinically important effects on dropout in group CBTs for patients with long-term conditions. It is unclear whether this intervention would also result in greater outcome improvements.

Effectiveness and reporting standards of psychological interventions for improving short-term and long-term pain outcomes after total knee replacement: a systematic review.

OBJECTIVES: To assess the effectiveness and reporting standards of psychological interventions for improving outcomes after total knee replacement (TKR). DESIGN: Medline, Embase, and PsycINFO were searched from inception to up to 9 May 2019 with no language restrictions applied. Randomised controlled trials (RCTs) assessing the effectiveness of psychological interventions for short-term and long-term postoperative pain after TKR were included. Screening, data extraction, and assessment of methodological quality were performed in duplicate by two reviewers. The primary effectiveness outcome was postoperative pain severity and the primary harm outcome was serious adverse events. Secondary outcomes included function, quality of life, and psychological well-being. Reporting standards were assessed using the Template for Intervention Description and Replication (TIDieR) checklist for intervention reporting. RESULTS: 12 RCTs were included, with a total of 1299 participants. Psychological interventions comprised music therapy (five studies), guided imagery and music (one study), hypnosis (one study), progressive muscle relaxation with biofeedback (one study), pain coping skills programme (one study), cognitive-behavioural therapy (two studies), and a postoperative management programme (one study). Due to the high heterogeneity of interventions and poor reporting of harms data, it was not possible to make any definitive statements about the overall effectiveness or safety of psychology interventions for pain outcomes after TKR. CONCLUSION: Further evidence about the effectiveness of psychological interventions for improving pain outcomes after TKR is needed. The reporting of harm outcomes and intervention fidelity is currently poor and could be improved. Future work exploring the impact of intervention timing on effectiveness and whether different psychological approaches are needed to address acute postoperative pain and chronic postoperative pain would be of benefit.
