A systematic review of the effectiveness of meaning-centred psychotherapies in depressed participants.

Depression is a mental disorder that is associated with low quality of life, increased risk of suicide and a high economic cost for society. Meta-analyses indicate that Meaning Centred Psychotherapies (MCP) are an efficacious psychotherapy to reduce depression in participants with chronic illness and cancer. However, to date, no systematic review has analysed the effectiveness of MCP in depressed participants who do not have a physical illness or cancer. The objective of this study was to carry out a systematic review to analyse the effectiveness of MCP in participants with depression and no physical illness. The search was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). Six studies (two randomised controlled trials and four quasi-experimental studies) were included in the systematic review. The results indicate that MCP is more effective than a control group as waitlist (four studies), psychoeducation group (one study), and cognitive behavioural therapy (CBT, one study), in reducing depressive symptoms, improving meaning in life and reducing anxiety in participants without physical illness. MCP would be considered a probably efficacious treatment for depression. However, further research with better experimental designs will be necessary to confirm the effectiveness of MCP for depression.

Family connections vs treatment at usual optimized in the treatment of relatives of people with suicidal behavior disorder: study protocol of a randomized control trial.

BACKGROUND: Relatives of people diagnosed with suicidal behavior disorder (SBD) feel guilty, afraid, hopeless, depression and anxiety. It is necessary to help the relatives of people with SBD to reduce their discomfort and burden. Family Connections (FC) is a program that has been shown to be effective in reducing burden, depression, and anxiety, and increasing dominance and validating behaviors in relatives of people with borderline personality disorder. However, there are no RCTs that demonstrate the efficacy of the FC program in patients with SBD. Our research team adapted FC for relatives of people with SBD for delivery in the Spanish population (FC-SBD). The FC-SBD program contains 12 two-hour sessions held once a week. The first aim is to verify the efficacy of the FC-SBD intervention for relatives of people diagnosed with SBD in a randomized control trial with a Spanish sample. The second objective is to analyze the feasibility and acceptance of FC-SBD in relatives. The third aim is to analyze whether the changes produced in the psychological variables in the relatives after the intervention are related to changes in the psychological variables of the patients. This paper presents the study protocol. METHODS: The study design consists of a two-arm randomized controlled trial with two conditions: FC-SBD or Treatment as usual optimized (TAU-O). Participants will be relatives of patients who meet DSM-5 criteria for SBD. The caregivers` primary outcome measures will be the BAS. Secondary outcomes will be DASS-21, FES, DERS, QoL. The patient's primary outcome measures will be the frequency of critical incidents with the family member with SBD. Secondary measures will be the INQ, PHQ-9, OASIS. Participants will be assessed at pretreatment, post-treatment, and 6-month follow-up. The intention-to-treat principle will be used when analyzing the data. DISCUSSION: This study will provide results that confirm the efficacy of the FC-SBD in relatives of people with SBD. These results will also confirm its good acceptance by family members and help us to find out whether it is a good program to improve the prevention of suicidal behaviors in the family environment.

Resilience as a predictor of quality of life in participants with borderline personality disorder before and after treatment.

BACKGROUND: Studies have suggested that psychotherapy improves the Quality of Life (QoL) of participants with Borderline Personality Disorder (BPD). However, there are no studies on the differential efficacy of treatments on the QoL of participants with BPD. Moreover, the relationship between QoL and resilience has rarely been studied in participants with BPD. OBJECTIVES: a) to examine whether people with BPD have worse QoL than the non-clinical population; b) to examine whether there are statistically significant differences between Dialectical Behavioural Therapy (DBT), Systems Training for Emotional Predictability and Problem Solving (STEPPS), or Cognitive Behavioural Therapy-Treatment at Usual (CBT-TAU) in the improvement of QoL; c) to examine whether participants show clinically significant improvements in QoL after treatment; d) to analyse whether resilience is associated with QoL before and after the BPD treatment; e) to analyse whether resilience is a predictor of QoL at pre-treatment and posttreatment. METHOD: The sample comprised 403 participants (n = 202 participants diagnosed with BPD and n = 201 non-clinical). Participants filled out the Quality of Life Index, Resilience Scale, and Beck Depression Inventory. The clinical participants received one of these possible treatments, DBT, STEPPS, or CBT-TAU. MANOVA and regression analyses were performed. RESULTS: a) participants diagnosed with BPD had statistically significant lower resilience than the non-clinical population; b) all three forms of psychotherapy statistically improved QoL, but there were no statistically significant differences between DBT, STEPPS, and CBT-TAU in the improvement of QoL; c) participants did not show clinically significant improvements in QoL after treatment; d) resilience was associated with QoL before and after treatment; and e) resilience was a predictor of QoL before and after treatment. CONCLUSION: It is necessary to assess QoL and Resilience in studies on psychotherapy with BPD patients.

Interventions for Family Members and Carers of Patients with Borderline Personality Disorder: A Systematic Review.

Carers of patients with borderline personality disorder (BPD) experience high levels of distress. Several studies have been carried out on interventions designed to decrease their burden. However, the evidence from these studies has not been summarized. The objective of this work is to explore the clinical utility of interventions developed for family members of patients with BPD. A systematic review was conducted following the PRISMA guidelines (registration number CRD42018107318), including psychological interventions focused on relatives of patients with BPD. The following databases were used: PsycINFO, PubMed, EBSCOhost, and Web of Science. Two independent researchers reviewed the studies to determine whether the eligibility criteria were met. A total of 2,303 abstracts were identified. After duplicates had been removed, 1,746 studies were screened. Finally, 433 full-text articles were reviewed, yielding 11 studies that satisfied the inclusion criteria. Results show that these interventions with different clinical formats and settings are effective. The quality of the included studies varies, and the empirical support for these programs is still preliminary. The results help to establish a general framework for interventions specifically developed for family members of patients with BPD, but additional efforts should be made to improve the methodological quality of this field of research and more solidly determine the utility of these interventions. Given the paucity of data so far, this information may open up new lines of research to improve the effectiveness of future programs for carers of patients with BPD and help to reduce their burden.

Los familiares de pacientes con trastorno límite de la personalidad (TLP) experimentan elevados niveles de estrés. Se han llevado a cabo varios estudios sobre intervenciones diseñadas para disminuir su carga. Sin embargo, los datos obtenidos de estos estudios no se han expuesto. El objetivo de este trabajo es explorar la utilidad clínica de las intervenciones desarrolladas para los familiares de los pacientes con TLP. Se realizó una revisión sistemática siguiendo las directrices de PRISMA (número de registro CRD42018107318), que incluyó intervenciones psicológicas centradas en los familiares de los pacientes con TLP. Se utilizaron las siguientes bases de datos: PsycINFO, PubMed, EBSCOhost, y Web of Science. Dos investigadores independientes revisaron los estudios para determinar si se cumplían los criterios de elegibilidad. Se identificaron un total de 2303 resúmenes. Después de extraer los duplicados, se evaluaron 1746 estudios. Finalmente, se revisaron 433 artículos de texto completo, lo que dio lugar a 11 estudios que cumplían los criterios de inclusión. Los resultados demuestran que estas intervenciones con diferentes formatos y orientaciones clínicas son eficaces. La calidad de los estudios incluidos varía, y el apoyo empírico para estos programas es todavía preliminar. Los resultados contribuyen a establecer un marco general para las intervenciones desarrolladas específicamente para los familiares de los pacientes con TLP, pero se deberían realizar esfuerzos adicionales para mejorar la calidad metodológica de este campo de investigación y determinar con mayor solidez la utilidad de estas intervenciones. Dada la escasez de datos hasta el momento, esta información puede abrir nuevas líneas de investigación para mejorar la eficacia de los futuros programas para los cuidadores de los pacientes con TLP y ayudar a reducir su carga.

Confirmatory factor analysis and psychometric properties of the Emotion Regulation Questionnaire in participants with personality disorders.

Emotional dysregulation is a key symptom in participants with personality disorders. The Emotional Regulation Questionnaire (ERQ) has been studied with nonclinical samples; however, it is necessary to confirm the factorial structure of the ERQ in participants with personality disorders. The aims of the present study were to confirm the factorial structure of the Spanish version of the ERQ and analyse its psychometric properties as well as the association between the ERQ and the Borderline Symptoms List (BSL-23) and the Difficulties in Emotion Regulation Scale (DERS). The overall sample was composed of 250 patients with personality disorders, of whom 195 met the criteria for borderline personality disorder. Confirmatory factor analysis was conducted. The two-factor model showed an acceptable fit, similar to the original structure, in the participants with personality disorders and with borderline personality disorder. Cognitive reappraisal was negatively correlated with the DERS and BSL-23, and expressive suppression was positively correlated with the BSL-23. The ERQ is a reliable and valid instrument to evaluate emotional dysregulation in participants with personality disorders and participants with borderline personality disorder.

Efficacy of "Family Connections", a program for relatives of people with borderline personality disorder, in the Spanish population: study protocol for a randomized controlled trial.

BACKGROUND: Patients with borderline personality disorder (BPD) experience significant affect regulation difficulties that cause serious consequences in their work, emotional, and social environments. This dysfunctional pattern also produces great suffering and a heavy burden on their relatives. Fortunately, some studies show that treatment of relatives of people with BPD begins to be important in the patients' recovery and in improving family dynamics. One of the treatments that has obtained the most empirical support is Family connections (FC). This 12-session program is an adaptation of different Dialectical Behavior Therapy strategies. To test the efficacy of FC, five uncontrolled clinical trials were conducted, with pre-post treatment and follow-up assessments. The results of these studies and subsequent replications showed an improvement in family attitudes and caregiver burnout. Our research team adapted FC for delivery in the Spanish population. We intend to test the efficacy of this program versus a treatment as usual condition. Moreover, we aim to test the efficacy of this program and study its effectiveness (in terms of participants' acceptance). This paper presents the study protocol. METHODS: The study is a randomized controlled trial. The participants will be recruited in a Personality Disorders Unit and randomly assigned to one of two treatment conditions: Family Connections group (FC) or Treatment As Usual (TAU). Primary outcome measures will be the BAS and FAD-GFS. Secondary outcomes will include DASS-21, FES, GS, and QLI. Participants' treatment acceptance and degree of satisfaction will also be measured. Participants will be assessed at pre-, post-treatment, and 6-month follow-up. Intention to treat and per protocol analyses will be performed. DISCUSSION: This is the first study on FC for relatives of people with borderline personality disorder (BPD) compared to an active condition (TAU), and this is the first time relatives' and patients' data will be analyzed. In addition, it is the first study to test the efficacy of the program in Spain. This intervention could contribute to improving the efficiency and effectiveness of current treatment programs for relatives of people with BPD, help to decrease burden, and improve the family connection.

Psychometric properties of the Spanish version of the involvement evaluation questionnaire in caregivers of patients with borderline personality disorders.

The involvement evaluation questionnaire (IEQ) was created to evaluate the caregiver's experience of burden and the consequences of providing care to people with psychotic disorders. To date, the IEQ has not been validated with caregivers of people diagnosed with borderline personality disorder (BPD). The main objective of the study was to confirm the psychometric properties and factorial structure of the Spanish version of the IEQ in 151 caregivers of people with BPD, with an average age of 54.52 (SD = 9.91). Two models were tested by means of confirmatory factor analysis, following the original factor structure. The Models 1 and 2 displayed adequate fit, with comparative fit index and Tucker-Lewis index > 0.90 and root-mean-square root of approximation < 0.08; however, Model 2 was more parsimonious. The Cronbach's alphas are adequate, ranging from 0.70 to 0.85. The consequences of providing care to people with BPD had a low or moderate association with the Level of Expressed Emotion scores. IEQ scores of caregivers of people diagnosed with BPD with psychiatric comorbidity did not differ from those of caregivers of people diagnosed with BPD without psychiatric comorbidity. The IEQ has adequate psychometric properties and can be utilized to assess burden in caregivers of people with BPD.

What do stakeholders understand by self-determination? Consensus for its evaluation.

BACKGROUND: Advances in international studies on self-determination point out the need for continuous efforts to deepen its understanding and implications. The aim of this study is to obtain a comprehensive pool of items to operationalize the self-determination construct that serves as a starting point towards a valid instrument based on the reports of others. METHOD: We conducted a Delphi study of three rounds involving three panels of experts: ten professionals, five people with intellectual disability and six relatives of people with intellectual disability. Data analysis required both qualitative and quantitative methods. RESULTS: The initial pool of 131 items was refined through the different rounds to a final set composed of 115-some were removed and new ones were added. Content-based evidence is provided. In this study, the present authors generated a potential valid pool of items to develop a new measurement tool based on the latest advances on the self-determination theoretical framework. CONCLUSIONS: The implications for future research focus on strengthening the knowledge of self-determination.

Examining measurement invariance and differences across groups in the support needs of children with and without intellectual disability.

BACKGROUND: The purposes of this study were to empirically determine whether the support needs construct is generalizable across children with and without intellectual disability and to conduct cross-group comparisons to explore how extraordinary and non-extraordinary support needs differ in children. METHOD: One thousand thirty-six children (814 with intellectual disability 222 without intellectual disability) were assessed using the SIS-C. RESULTS: The SIS-C achieved scalar invariance between children with and without intellectual disability. Cross-group comparisons revealed differences in variances, in correlations between factors and significant latent mean differences for all factors. CONCLUSION: Results show that the support needs construct is generalizable to children with and without intellectual disability and that there are no qualitative differences in how they show their support needs, so typically developing children can be used as a reference group to explore differences between extraordinary and non-extraordinary support needs. Conceptual and practical implications are discussed, and future lines of research are provided.

Recent Progress in Virtual Reality Exposure Therapy for Phobias: A Systematic Review.

This review is designed to systematically examine the available evidence about virtual reality exposure therapy's (VRET) efficacy for phobias, critically describe some of the most important challenges in the field and discuss possible directions. Evidence reveals that virtual reality (VR) is an effective treatment for phobias and useful for studying specific issues, such as pharmacological compounds and behavioral manipulations, that can enhance treatment outcomes. In addition, some variables, such as sense of presence in virtual environments, have a significant influence on outcomes, but further research is needed to better understand their role in therapeutic outcomes. We conclude that VR is a useful tool to improve exposure therapy and it can be a good option to analyze the processes and mechanisms involved in exposure therapy and the ways this strategy can be enhanced. In the coming years, there will be a significant expansion of VR in routine practice in clinical contexts.

Personal Factors, Living Environments, and Specialized Supports: Their Role in the Self-Determination of People with Intellectual Disability.

The self-determination of people with disabilities, and specifically people with intellectual disabilities (ID), is a growing issue due to its relevance in the field of inclusion and human rights. Although research has shown a significant relationship between self-determination and intelligence, other factors also contribute to its development. The purpose of this study was to understand what other variables may be influencing self-determination. Using the scores from 483 adolescents and adults with ID who completed the AUTODDIS scale, we performed inferential and regression analyses to determine the relationships between levels of self-determination, personal variables (sex, age, severity of ID), and contextual variables (living environment, specialized supports). We found that self-determination is affected by the severity of ID, and when this variable is controlled for, greater self-determination is mainly related to receiving occupational support and support for autonomy and independent living. Results also showed that, together with ID severity, occupational and psychoeducational support, as well as support for autonomy and independent living, were also predictors of the level of self-determination. In conclusion, this study confirms the importance of contextual variables in the development of self-determination in people with ID, placing the focus of intervention on social opportunities.

A measurement of self-determination for people with intellectual disability: description of the AUTODDIS scale and evidences of reliability and external validity.

Background: Appropriate supports and instructional practices contribute to the development of self-determination. Also, research shows that the promotion of skills related to self-determination has been linked to the achievement of desired outcomes over the different life stages. Advances in self-determination require the development of assessment instruments because there is a reciprocal relationship between assessment and instruction. The purpose of this paper is to provide a description of the AUTODDIS Scale, along with evidence of its reliability and external validity. Method: A sample of 541 people with intellectual disabilities aged from 11 to 40 was used to validate the scale. Results: The reliability results indicate that the AUTODDIS Scale shows high internal consistency. The total score and subscale scores indicate moderate inter-rater reliability. The scores were also moderately to highly associated with other related measures of self-determination and quality of life (QoL). Conclusion: Our results demonstrate that consistent and valid information can be obtained from the AUTODDIS Scale.

Support Needs of Children with Autism Spectrum Disorders: Implications for Their Assessment.

The construct of support needs has become a key aspect for the diagnostics, classification, and interventional management of autism spectrum disorders (ASDs). However, instruments specifically designed to assess support needs in this population are not available. Currently, the Supports Intensity Scale for Children (SIS-C), which could be administered to assess students with any type of intellectual disability (ID), is the only valid tool able to assess support needs in Spain. Our aim was to verify whether the SIS-C is useful for assessing the support needs of students with ASD, regardless of whether or not they present ID. The participants were subdivided into two groups. One group included students with ASD and ID (n = 248), and the other comprised participants with ASD without an ID (n = 44). The results of the two groups were compared with those reported in the original validation sample of the SIS-C, which involved participants with ID without ASD (n = 566). The results showed that this scale could be useful for assessing support needs in the three subgroups, but it appeared that different standardized norms based on the characteristics of each specific population would be appropriate.

Spanish adaptation of the Burden Assessment Scale in family caregivers of people diagnosed with borderline personality disorder.

BACKGROUND: Caregiving is a strong source of stress and leads the family caregiver to experience the burden of being responsible for the care of a severely mentally ill family member. The Burden Assessment Scale (BAS) assesses burden in family caregivers. This study aimed to analyze the psychometric properties of the BAS in a sample of family caregivers of people diagnosed with Borderline Personality Disorder (BPD). METHODS: Participants were 233 Spanish family caregivers (157 women and 76 men aged between 16-76 years old, M = 54.44, SD = 10.09) of people diagnosed with BPD. The BAS, the Multicultural Quality of Life Index, and the Depression Anxiety Stress Scale-21 were used. RESULTS: An exploratory analysis resulted in a three-factor 16-item model (Disrupted Activities; Personal and Social Dysfunction; Worry, Guilt, and Being Overwhelmed) with an excellent fit (χ2(101) = 56.873, p = 1.000, CFI = 1.000, TLI = 1.000, RMSEA = .000, SRMR = .060), good internal consistency (ω = .93), a negative correlation with quality of life, and a positive correlation with anxiety, depression, and stress. CONCLUSION: The model obtained for the BAS is a valid, reliable, and useful tool for assessing burden in family caregivers of relatives diagnosed with BPD.

Family connections in the treatment of relatives of people with eating disorders and personality disorders: study protocol of a randomized control trial.

BACKGROUND: Eating disorders (EDs) are serious disorders that significantly affect not only the lives of patients, but also those of their family members who often experience high levels of burden, suffering and helplessness. If, in addition to ED, the patient has a personality disorder (PD), the psychological distress experienced by family members can be devastating. However, few treatments have been developed for family members of people with ED and PD. Family Connections (FC) is a programme that has been shown to be effective for family members of people with borderline personality disorder. The overall aims of this work are: (a) to adapt FC for application to family members of patients with BPD-PD (FC: ED-PD); (b) to analyse, in a randomised controlled clinical trial, the efficacy of this programme in a Spanish population, compared to a control condition consisting of treatment as usual optimised treatment (TAU-O); (c) to analyse the feasibility of the intervention protocol; (d) to analyse whether the changes that may occur in relatives are related to improvements in the family climate and/or improvements observed in patients; and (e) to analyse the perceptions and opinions of relatives and patients about the two intervention protocols. METHODS: The study uses a two-arm randomised controlled clinical trial with two experimental conditions: adaptation of FC programme (FC: ED-PD) or Treatment as usual optimised (TAU-O). Participants will be family members of patients who meet DSM-5 criteria for ED and PD or dysfunctional personality traits. Participants will be assessed before and after treatment and at one-year follow-up. The intention-to-treat principle will be used when analysing the data. DISCUSSION: The results obtained are expected to confirm the effectiveness of the programme and its good acceptance by family members. Trial registration ClinicalTrials.gov Identifier: NCT05404035. Accepted: May 2022.

Difficulties in emotional regulation mediates the impact of burden on quality of life and mental health in a sample of family members of people diagnosed with Borderline Personality Disorder.

Background: Although it has been suggested that family members of persons suffering from Borderline Personality Disorder (BPD) endure high levels of burden, however, the process and the impact of this burden in their lives, and specifically the relation between the burden and emotional regulation has not been broadly investigated among this population. The main objective of this study is to examine the impact of burden on quality of life and depression, anxiety and stress, as mediated by difficulties in emotional regulation in family members of persons diagnosed with BPD. Method: Participants were 167 family members of persons diagnosed with BPD. The Burden Assessment Scale, Difficulties in Emotion Regulation Scale, Multicultural Quality of Life Index, and Depression Anxiety Stress Scale-21 were filled out. Mediation analysis was conducted using the Maximum Likelihood estimator, bootstrap method and listwise deletion for missing data. Results: Burden showed a significant, negative effect on quality of life and positive on depression, anxiety and stress. Difficulties in emotion regulation significantly mediated these relations. After accounting for the mediating role of difficulties in emotion regulation, burden still had an impact on quality of life, depression, anxiety and stress. Women showed a higher level in both burden and stress than men. The caregivers with secondary and higher studies showed higher levels in burden than those with no studies. Not significant differences in burden, emotion regulation, depression, anxiety and stress were found related to marital status. Conclusion: Difficulties in emotion regulation mediate the relations between burden and quality of life, depression, anxiety, and stress. Family members could engage in group interventions designed specifically for family members of people with BPD, oriented toward understanding the disorder or learning skills.

Mindfulness Component in a Dialectical Behavioural Therapy Group Intervention for Family Members of Borderline Personality Disorder Patients.

BACKGROUND: Family members of people with borderline personality disorder (BPD) are seriously affected by the disease and it is common for them to ask for professional help. The main objective of this study is to assess, in an open clinical trial, a treatment protocol based on Dialectical Behaviour Therapy (DBT) strategies for relatives of individuals with BPD, compared to the same protocol plus a mindfulness component (DBT-M). METHOD: The interventions were conducted in a sample of 108 relatives of 83 patients diagnosed with BPD from a Specialized Unit for Personality Disorders. Relatives and patients completed the assessment protocol before and after the intervention. RESULTS: Significant improvements in almost all the relevant variables tested were observed after the treatment in both the relatives and the patients. However, there were only statistically significant differences between the groups in the negative attitude towards the illness, where relatives in the DBT-M condition showed greater improvement than those in the DBT condition. CONCLUSIONS: The results indicate that the intervention helps both patients and relatives to improve on key issues. It is essential to consider and offer support to the families of people with severe psychological disorders.

Psychometric Properties of the Interpersonal Needs Questionnaire-15 in Spanish Adolescents.

Background: Thwarted Belongingness (TB) and Perceived Burdensomeness (PB) are considered risk factors of suicide behavior in the Interpersonal Theory of Suicide and constitute the main factors of the Interpersonal Needs Questionnaire-INQ. Aims: The present study analyzes the internal consistency, construct validity, and invariance across sex and age of the INQ-15, which comprises two subscales, in a sample of Spanish community adolescents. Methods: Participants were 1,536 adolescents from 12 to 19 years old. The INQ-15, the total number of non-suicidal self-injuries (NSSI), the Hopelessness Scale, and the Purpose in Life Test-Adolescents (PIL-A) were used. Results: The INQ-15 showed good internal consistency for TB ( ω ¯ = 0.88) and PB ( ω ¯ = 0.78) subscales and construct and concurrent/discriminant validity in the whole sample. Both the PB and TB subscales showed a good fit { S B χ 2 ( 9 ) = 6.448, p = 0.694, CFI = 1.000, RMSEA = 0.000 [90% CI (0.000, 0.022)] and S B χ 2 ( 27 ) = 248.973, p = 0.000, CFI = 0.922, RMSEA = 0.073 [90% CI (0.065, 0.082)]}, respectively. Regarding the invariance analyses, we found (1) non-invariance in the PB subscale across sex groups and metric, scalar, and stric invariance across age groups, and (2) that it was not possible to perform the invariance analysis for the TB subscale across both sex and age because the fit was not adequate for both boys and 12-15 years old groups. Positive and significant relationships were found between the INQ-15 subscales and hopelessness and NSSI frequency, and negative and significant correlations with meaning in life. Conclusions: The INQ-15 is a valid instrument for assessing TB and PB in Spanish adolescents. Future studies should analyze the invariance of this instrument in adolescents across sex and age.

Multicultural Quality of Life Index in Relatives of People With Borderline Personality Disorder.

Purpose: The aim of the present study was to confirm the original factor structure of the Multicultural Quality of Life Index (MQLI) and analyze its psychometric properties in a sample of caregivers of people with borderline personality disorder (BPD). Methods: The MQLI was administered to 233 relatives of people with BPD. Participants completed the MQLI, the Depression, Anxiety and Stress Scale (DASS-21), and the Connor-Davidson Resilience Scale (CD-RISC). Results: Factor analysis of the relatives indicated that the MQLI generated a one-factor solution. The MQLI showed good internal consistency, ϖ = 0.91 [95% CI (0.90, 0.93)] and correlated significantly and positively with the CD-RISC (r s = 0.576) and negatively with the DASS-21 (r s = -0.583). Conclusion: Consistent with other studies, the MQLI demonstrated feasibility, strong internal consistency, and good convergent and discriminant validity, which means it is a psychometrically robust measure for the assessment of quality of life in relatives of people with BPD. Along with other validation studies, this measure will be a useful tool for assessing quality of life in relatives of people with mental disorders.
