Evaluation of heroin-assisted treatment in Norway: protocol for a mixed methods study.

BACKGROUND: Opioid agonist treatment (OAT) for patients with opioid use disorder (OUD) has a convincing evidence base, although variable retention rates suggest that it may not be beneficial for all. One of the options to include more patients is the introduction of heroin-assisted treatment (HAT), which involves the prescribing of pharmaceutical heroin in a clinical supervised setting. Clinical trials suggest that HAT positively affects illicit drug use, criminal behavior, quality of life, and health. The results are less clear for longer-term outcomes such as mortality, level of function and social integration. This protocol describes a longitudinal evaluation of the introduction of HAT into the OAT services in Norway over a 5-year period. The main aim of the project is to study the individual, organizational and societal effects of implementing HAT in the specialized healthcare services for OUD. METHODS: The project adopts a multidisciplinary approach, where the primary cohort for analysis will consist of approximately 250 patients in Norway, observed during the period of 2022-2026. Cohorts for comparative analysis will include all HAT-patients in Denmark from 2010 to 2022 (N = 500) and all Norwegian patients in conventional OAT (N = 8300). Data comes from individual in-depth and semi-structured interviews, self-report questionnaires, clinical records, and national registries, collected at several time points throughout patients' courses of treatment. Qualitative analyses will use a flexible inductive thematic approach. Quantitative analyses will employ a wide array of methods including bi-variate parametric and non-parametric tests, and various forms of multivariate modeling. DISCUSSION: The project's primary strength lies in its comprehensive and longitudinal approach. It has the potential to reveal new insights on whether pharmaceutical heroin should be an integral part of integrated conventional OAT services to individually tailor treatments for patients with OUD. This could affect considerations about drug treatment even beyond HAT-specific topics, where an expanded understanding of why some do not succeed with conventional OAT will strengthen the knowledge base for drug treatment in general. Results will be disseminated to the scientific community, clinicians, and policy makers. TRIAL REGISTRATION: The study was approved by the Norwegian Regional Committee for Medical and Health Research Ethics (REK), ref.nr.:195733.

Managing depressive symptoms in people with mild cognitive impairment and mild dementia with a multicomponent psychotherapy intervention: a randomized controlled trial.

OBJECTIVE: To evaluate the feasibility and effectiveness of the CORDIAL program, a psychosocial intervention consisting of cognitive behavioral therapy (CBT), cognitive rehabilitation, and reminiscence to manage depressive symptoms for people with mild cognitive impairment (MCI) or dementia. DESIGN: We conducted a randomized controlled trial, based on a two-group (intervention and control), pre-/post-intervention design. SETTING: Participants were recruited from five different old age psychiatry and memory clinics at outpatients' hospitals. PARTICIPANTS: Hundred and ninety-eight people with MCI or early-stage dementia were included. INTERVENTION: The intervention group (n = 100) received 11 individual weekly sessions of the CORDIAL program. This intervention includes elements from CBT, cognitive rehabilitation, and reminiscence therapy. The control group (n = 98) received treatment-as-usual. MEASUREMENTS: We assessed Montgomery-Åsberg Depression Rating Scale (MADRS) (main outcome), Neuropsychiatric Inventory Questionnaire, and Quality of Life in Alzheimer's disease (secondary outcomes) over the course of 4 months and at a 10-month follow-up visit. RESULTS: A linear mixed model demonstrated that the depressive symptoms assessed by MADRS were significantly more reduced in the intervention groups as compared to the control group (p < 0.001). The effect persisted for 6 months after the intervention. No significant differences between groups were found in neuropsychiatric symptoms or quality of life. CONCLUSION: Our multicomponent intervention, which comprised 11 individual sessions of CBT, cognitive rehabilitation, and reminiscence therapy, reduced depressive symptoms in people with MCI and dementia.

A multi-center psychometric evaluation of the Severity Indices of Personality Problems 118 (SIPP-118): Do we really need all those facets?

PURPOSE: The Severity Indices of Personality Problems 118 (SIPP-118) is a self-report questionnaire that aims to measure core components of (mal)adaptive personality functioning that can change over time. In this study, we aimed to assess the facet strength of the 16 facets across three large clinical samples. METHODS: Data from Norwegian and Dutch psychiatric patients were analyzed in this international multi-center study (N1 = 2814, N2 = 4751, N3 = 2217). Bi-factor modeling was used to assess to what degree the SIPP items tap into an overall general factor. The incremental value (distinctiveness) of the facets was studied using proportional reduction in mean squared error (PRMSE) based statistics. RESULTS: The estimated model showed adequate fit. The explained common variance (ECV) attributable to the general factor equaled 50% for all three samples. All but two facets (stable self-image and frustration tolerance) showed sufficient levels of distinctiveness. The findings were observed to be comparable across the three samples. CONCLUSION: Our findings showed that the general factor was relatively weak, and the facets had a clear incremental value.

Effect of Self-Efficacy on Quality of Life in People With Mild Cognitive Impairment and Mild Dementia: The Mediating Roles of Depression and Anxiety.

OBJECTIVES: To examine the mediating effects of depression and anxiety in the relationship between self-efficacy and quality of life among people with mild cognitive impairment (MCI) or mild dementia. METHOD: A total of 196 patients diagnosed with MCI or dementia due to Alzheimer disease completed structured measures of self-efficacy, quality of life, and depressive and anxiety symptoms. We examined direct and mediated effects by fitting structural equation models to data. RESULTS: Our analyses supported that the effects of self-efficacy on quality of life may be partially mediated by depression and anxiety. Both anxiety and depression had significant mediating effects, with depression showing a stronger effect. CONCLUSION: These results suggest that increased self-efficacy may have a positive effect on quality of life in people with MCI or dementia-partly by reducing depression and anxiety. These findings may have important practical implications for tailoring therapeutic interventions.

Anabolic androgenic steroid dependence is associated with impaired emotion recognition.

RATIONALE: Illicit use of anabolic androgenic steroids (AAS) has grown into a serious public health concern throughout the Western World. AAS use is associated with adverse medical, psychological, and social consequences. Around 30% of AAS users develop a dependence syndrome with sustained use despite adverse side effects. AAS dependence is associated with a high frequency of intra- and interpersonal problems, and it is central to identify factors related to the development and maintenance of dependence. METHODS: The present study investigated the ability to recognize emotion from biological motion. The emotional biological motion task was administered to male AAS dependent users (AAS dependents; n = 45), AAS non-dependent users (AAS non-dependents; n = 38) and a comparison-group of non-using weightlifters (non-users; n = 69). RESULTS: Multivariate analysis of variance showed a general impairment in emotion recognition in AAS dependents, compared to the non-using weightlifters, whereas no significant impairment was observed in AAS non-dependents. Furthermore, AAS dependents showed impaired recognition of fearful stimuli compared to both AAS non-dependents and non-using weightlifters. The between-group effect remained significant after controlling for Intelligence Quotient (IQ), past 6 months of non-AAS drug use, antisocial personality problems, anxiety, and depression. CONCLUSION: AAS dependents show impaired emotion recognition from body movement, fear in particular, which could potentially contribute to higher frequency of interpersonal problems and antisocial behaviors in this population.

Contribution of the patient-horse relationship to substance use disorder treatment: Patients' experiences.

BACKGROUND: A good therapeutic relationship is a strong predictor of successful treatment in addiction and other psychological illness. Recent studies of horse-assisted therapy (HAT) have drawn attention to the importance of the client's relationship to the horse in psychotherapy. Few have reported on the patient's own perspective and none have reported specifically on the human-horse relationship in substance use disorder (SUD) treatment and its implications for health and well-being. AIM: This article explores SUD patients' own experience of their relationship with the horse and their perceptions of its contribution to their therapy. METHODS: As part of a large mixed-method study of HAT in SUD treatment, we used semi-structured interviews of eight patients to gather information about their experiences of HAT. From the data obtained, the relationship with the horse was found to be a significant part of participants' HAT experience. It is therefore the subject of the current phenomenological study, in which thematic analysis was used to investigate how the participants constructed the reality of their relationship with the horse(s) and their perceptions of the consequences of that reality in SUD treatment. RESULTS: Participants' own descriptions suggest that the horses were facilitators of a positive self-construct and provided important emotional support during treatment. Analysis found relationship with the horse, emotional effect, and mastery to be important and interrelated themes. The findings were interpreted within an attachment theory context. CONCLUSION: The results appear to be consistent with key addiction treatment theories and with findings in HAT theoretical and empirical studies. They add to our understanding of the impact of HAT on SUD treatment. However, further research is needed into both the construct validity of the patient-horse therapeutic relationship and the possible variance within and between different populations.
