Perceived Change Processes in Dialectical Behaviour Therapy From the Perspective of Clients With a Diagnosis or Traits of Borderline Personality Disorder: A Systematic Literature Review.

PURPOSE: To synthesise qualitative research on individuals diagnosed with (or reportedly showing traits of) borderline pattern personality disorder who underwent dialectical behaviour therapy, aiming to comprehend their perceptions of change processes and the therapy's effects. METHOD: A comprehensive literature search was conducted across multiple online databases and grey literature sources. Papers were quality appraised using an adapted version of the Critical Appraisal Skills Programme tool. A metaethnographic approach was employed during the synthesis. RESULTS: Eleven studies met criteria for inclusion in the review. The main themes identified through the synthesis process were the impact of DBT, the supportive structure and the 1:1 therapy component. CONCLUSIONS: The synthesis uncovered the importance of various processes within DBT that patients perceived as active ingredients for their change. Many of these processes aligned with proposed theoretical processes of change and quantitative research on DBT's effectiveness.

Barriers and strategies to medication adherence amongst people with multiple sclerosis and cognitive problems.

BACKGROUND: Adherence to disease-modifying treatment (DMT) amongst people with multiple sclerosis (MS) varies greatly. Although research often identifies 'forgetting' as a reason for poor adherence, few studies have considered how cognitive problems impact adherence. OBJECTIVES: To investigate prevalence of and barriers to adherence, including for people with MS-related cognitive problems, and to identify adherence-related strategies. METHODS: Recruited via the UK MS Register and MS Society groups, participants completed a Medication Adherence Questionnaire and the Perceived Deficits Questionnaire. A subset were interviewed. RESULTS: Of 257 participants, 94 % reported being adherent, although 59 % missed ≥1 dose, and 25 % reported cognitive problems. Adherence was lower amongst those with cognitive problems, who experienced more barriers: memory problems; negative feelings about taking medication; and not wanting medication to interfere with activities. Such barriers, along with mood, cognition, and method of DMT administration, explained 17 % of variance in adherence, with intravenous treatment a significant predictor. Cognitive problems explained a unique proportion of variance; however, was non-significant when anxiety was factored in. Interviews highlighted how anxiety about side-effects and injections, and difficulties accepting the diagnosis, hindered use of reminders. CONCLUSION: Interventions for cognition and mood problems, minimising treatment burden and supporting adjustment to diagnosis, may improve adherence.

A Systematic Quality Review of Single-Case Experimental Designs Using Acceptance and Commitment Therapy in Adult Clinical Populations.

Recent publications within Contextual Behavioral Science provided a rationale for the expansion of intervention efficacy research using methods that capture idiographic factors and processes. We conducted a systematic review of the use and quality of single-case experimental designs (SCED) within the Acceptance and Commitment Therapy (ACT) literature in adult clinical populations. The systematic review was conducted according to PRISMA guidelines and the databases CINAHL, MEDLINE, PsycINFO, PsycArticles and OpenGrey were searched for peer-reviewed articles. Further studies were sought through review of reference lists of all full text studies. Studies were assessed against What Works Clearinghouse (WWC) single-case design standards. Twenty-six studies met eligibility criteria and were conducted within research teams all implementing multiple-baseline designs. Twenty-four studies did not meet WWC standards with most failing to ensure a degree of concurrence across participants. The extent of randomisation methods was also captured. The review highlights the sparsity of SCEDs within ACT literature in clinical populations and current methodological practices. Limitations of the review and implications for future research are discussed.
