- Chronic loneliness is associated with a range of mental health difficulties. Previous theory and research indicate that psychological interventions show promise for reducing loneliness, however, there have been no systematic reviews or meta-analyses to ascertain the efficacy of these interventions across the lifespan. The aim of this study was to synthesise, meta-analyse and explore the heterogeneity in RCTs of psychological interventions for loneliness in order to establish their efficacy. Five databases (Ovid Embase, Ovid Medline, PsycINFO, Web of Science and CINAHL) were systematically searched in order to identify relevant studies. Included studies were required to be peer-reviewed RCTs examining psychological interventions for loneliness. Two independent coders examined the abstracts of the 3973 studies and 103 full texts, finding 31 studies that met inclusion criteria, 28 of which contained sufficient statistical information to be included in the meta-analysis. The quality of included studies was assessed using the Cochrane Risk of Bias Tool. The 31 studies (N = 3959) that were included in the systematic review were conducted with participants from a diverse range of cultures, age groups and populations. The interventions were of mixed quality and were mostly face to face, group-based and delivered weekly. The most common type of intervention was Cognitive Behavioural Therapy (CBT). 28 studies (N = 3039) were included in a meta-analysis which found that psychological interventions significantly reduced loneliness compared to control groups, yielding a small to medium effect size (g = 0.43). Subgroup analysis and meta-regressions were conducted in order to explore heterogeneity and found that type of psychological intervention was approaching significance as a moderator of the effectiveness of psychological interventions for loneliness. In conclusion, psychological interventions for loneliness across the lifespan are effective. This finding should inform policy makers, researchers and clinicians going forward, especially in the context of increased loneliness due to the COVID-19 pandemic. There was considerable heterogeneity in the effectiveness of the interventions, suggesting that future research should also explore what works for whom and consider personalising psychological treatment.

- Loneliness is a common experience in populations experiencing mental health problems. Associations with symptoms of psychopathology are prevalent, but little is known about the diversity of symptom profiles in people suffering from prolonged and distressing loneliness. The current study sought to investigate the existence of subgroups of loneliness and common forms of psychopathology in a sample of adults (n = 332) seeking treatment for their loneliness. Using latent profile analysis, five profiles were identified and differences in demographic factors were investigated. The profiles differed mainly in the severity of symptoms of depression, worry, and social anxiety, with the largest profile exhibiting minimal-to-mild symptoms (n = 109) across these indicators. The second largest group was characterized primarily by high ratings of social anxiety (n = 90). Overall, three of the five profiles, encompassing roughly half of the sample, scored at a clinical level on mental health symptom measures. Age was inversely related to symptom severity among the profiles, indicating that the older subgroups of the sample exhibited milder symptoms, particularly on social anxiety. The results provide insight into the heterogeneity of the clinical symptoms of people suffering from loneliness and add important knowledge that could help inform how to best intervene to help this population.

Internet-based interventions for loneliness : Efficacy and latent psychopathological profiles of treatment seekers
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Loneliness is an adverse emotional reaction thought to stem from an unwanted and impoverished social situation. Though it commonly makes brief appearances across the lifespan for most people, it has received increasing attention as a factor relevant to somatic and psychological well-being when assuming a more chronic form. For this reason, developing ways of alleviating loneliness is an important item on the research agenda tied to this phenomenon. Psychological interventions, and cognitive behavioural therapy (CBT) in particular, have been proposed to have potential for this. This thesis sought to evaluate the effects of two different kinds of internet-based interventions targeting loneliness: one based on CBT, and one based on interpersonal psychotherapy (IPT).In addition to this general aim, Study I also investigated the presence of different subgroups in the sample of people seeking help within the framework of projects. Using the statistical method known as Latent Profile Analysis we discovered five profiles consisting of symptoms of common psychiatric disorders and loneliness. The profiles mainly differed as a function of symptom severity, though one of the larger groups was also characterised primarily by their high ratings of social anxiety. The results suggest that the sample seeking help for their loneliness can exhibit both clinical and non-clinical levels of common mental health problems.Study II served as the pilot evaluation of an ICBT programme for loneliness. A total of 73 participants were included in a randomised controlled trial where the participants were randomised to either 8 weeks of active treatment or a wait-list control group. The results indicated significantly lower loneliness ratings after the treatment phase for the ICBT condition with a moderate-to-large effect size compared to the control group. Significant differences favouring the ICBT condition were also noted for two of the four secondary measures.Study III followed up on the participants two years after the conclusion of the initial treatment period. At this point, the control group had also received access to a version of the ICBT programme with therapist support on-demand. The results indicated that the decrease in loneliness was sustained, along with similarly lasting effects on the secondary outcomes of interest.Study IV aimed to replicate the findings from the second study with a similar ICBT programme. However, this study also employed an internet-based IPT intervention to allow for conclusions regarding the possibility of reducing loneliness by other means than CBT. A sample of 170 participants were recruited and randomised to one the treatment conditions or to a waitlist control group. The results indicated that the ICBT condition had a significantly steeper reduction in loneliness than both the waitlist and the IPT condition after the conclusion of the treatment. Both active conditions produced a significant increase in quality of life.In conclusion, internet-based psychological interventions can be efficacious for reducing loneliness, though the efficacy was only found for participants who received access to the ICBT condition in Study II and IV. The benefits from this treatment programme were sustained up to two years after the conclusion of the intervention. For these reasons, ICBT is proposed to be a good candidate for offering help to people experiencing distressing feelings of loneliness.

- Introduction: Chronic loneliness has been linked to many adverse outcomes, including mental health problems. Psychological treatment of loneliness can be effective, but the evidence base is limited. Objective: To investigate the efficacy of 2 internet-based interventions based on cognitive behavioral therapy (ICBT) and interpersonal psychotherapy (IIPT) relative to a wait-list control group and each other. Methods: A total of 170 participants were recruited and randomized to either 9 weeks of ICBT (n = 68), IIPT (n = 68), or a wait-list condition (n = 34). The primary outcome was loneliness, measured using the UCLA Loneliness Scale before, during, and after treatment. Secondary measures of psychiatric disorders and quality of life were administered before and after treatment. Follow-up was conducted 4 months after the treatment had ended. Primary outcome data were analyzed using growth curve modeling. Secondary outcomes were analyzed using robust regression models. The trial was preregistered (ClinicalTrials.gov ID: NCT03807154). Results: The ICBT condition had a significantly greater impact on loneliness compared to the wait-list and IIPT conditions. Effect sizes were moderate to large (Cohen d = 0.71) compared to the wait-list and moderate (d = 0.53) compared to IIPT. The IIPT condition did not differ significantly from the wait-list. Both active treatments led to significant increases in quality of life. Only the ICBT group had significantly lower symptoms of depression and generalized anxiety compared to the wait-list group. Treatment gains were maintained but not improved at follow-up. Conclusions: ICBT can be an efficacious option for alleviating loneliness. The IIPT intervention was not as effective.

- Background: Perfectionism is often defined as the strive for achievement and high standards, but can also lead to negative consequences. In addition to affecting performance and interpersonal relationships, perfectionism can result in mental distress. A number of different self-report measures have been put forward to assess perfectionism. Specifically intended for clinical practice and research, the Clinical Perfectionism Questionnaire (CPQ) was developed and is presently available in English and Persian. To promote its use in additional contexts, the current study has translated and investigated the psychometric properties of the Swedish version of the CPQ.Method: A Confirmatory Factor Analysis was performed to examine the best fit with data, using a priori-models and a sample of treatment-seeking participants screened for eligibility to receive Internet-based cognitive behavior therapy (n = 223).Results: The results indicated a lack of fit with data. A two-factor structure without the two reversed items (2 and 8) exhibited the best fit, perfectionistic strivings and perfectionistic concerns, but still had poor structural validity. Correlations with self-report measures of perfectionism, depression, anxiety, dysfunctional beliefs, self-criticism, quality of life, and self-compassion were all in the expected directions. Eight-week test-retest correlation was Pearson r = .62, 95% Confidence Interval [.45, .74], using data from 72 participants in the wait-list control, and the internal consistency for the CPQ, once removing the reversely scored items, was Cronbach’s α = .72.Conclusion: The CPQ can be used as a self-report measure in Swedish, but further research on its structural validity is needed.

Forskningsöversikt (refereegranskat)abstract
- Loneliness is a relatively common problem in young people (14-24 years) and predicts the onset of depression and anxiety. Interventions to reduce loneliness thus have significant potential as active ingredients in strategies to prevent or alleviate anxiety and depression among young people. Previous reviews have focused on quantitative evidence and have not examined potential mechanisms that could be targets for intervention strategies. To build on this work, in this review we aimed to combine qualitative and quantitative evidence with stakeholder views to identify interventions that appear worth testing for their potential effectiveness in reducing loneliness, anxiety and depression in young people aged 14-24 years, and provide insights into the potential mechanisms of action. We conducted a Critical Interpretative Synthesis, a systematic review method that iteratively synthesises qualitative and quantitative evidence and is explicitly focused on building theory through a critical approach to the evidence that questions underlying assumptions. Literature searches were performed using nine databases, and eight additional databases were searched for theses and grey literature. Charity and policy websites were searched for content relevant to interventions for youth loneliness. We incorporated elements of Rapid Realistic Review approaches by consulting with young people and academic experts to feed into search strategies and the resulting conceptual framework, in which we aimed to set out which interventions appear potentially promising in terms of theoretical and empirical underpinnings and which fit with stakeholder views. We reviewed effectiveness data and quality ratings for the included randomised controlled trials only. Through synthesising 27 studies (total participants n = 105,649; range 1-102,072 in different studies) and grey literature, and iteratively consulting with stakeholders, a conceptual framework was developed. A range of Intrapersonal (e.g. therapy that changes thinking and behaviour), Interpersonal (e.g. improving social skills), and Social Strategies (e.g. enhancing social support, and providing opportunities for social contact) seem worth testing further for their potential to help young people address loneliness, thereby preventing or alleviating depression and/or anxiety. Such strategies should be co-designed with young people and personalised to fit individual needs. Plausible mechanisms of action are facilitating sustained social support, providing opportunities for young people to socialise with peers who share similar experiences, and changing thinking and behaviour, for instance through building positive attitudes to themselves and others. The most convincing evidence of effectiveness was found in support of Intrapersonal Strategies: two randomised controlled studies quality-rated as good found decreases in loneliness associated with different forms of therapy (Cognitive Behavioural Therapy or peer network counselling), although power calculations were not reported, and effect sizes were small or missing. Strategies to address loneliness and prevent or alleviate anxiety and depression need to be co-designed and personalised. Promising elements to incorporate into these strategies are social support, including from peers with similar experiences, and psychological therapy.

The concept and definition of low intensity cognitive behaviour therapy
- 2021

Ingår i: Behaviour Research and Therapy. - : Elsevier BV. - 0005-7967 .- 1873-622X. ; 138

Tidskriftsartikel (refereegranskat)abstract
- There is confusion in the terminology used to describe different forms of cognitive behaviour therapy, in particular low intensity CBT. Such confusion has implications for research, clinical practice and service organisation. This thought-piece aims to describe the key components of low intensity CBT in comparison to brief high intensity standard CBT. It is proposed that low intensity CBT (i) utilises self-help materials, (ii) is six hours or less of contact time with each contact being typically 30 minutes or less, and (iii) any input can be provided by trained practitioners or supporters. These components distinguish the intervention from brief high intensity intensity CBT which (i) is based on the standard evidence-based CBT treatment, with therapy contact time 50% or less than the full CBT intervention, and (ii) is usually delivered by someone with a core mental health professional qualification or equivalent. Brief CBT can refer to either low intensity CBT and/or brief high intensity CBT. We hope that making the distinction between these different forms of intervention stimulates debate and helps consistent and appropriate categorisation for future research and practice.
