Mental health problems and suicidal behavior from adolescence to young adulthood in college: linking two population-based studies.

It is well established that mental health problems are highly recurrent and persistent from childhood to adolescence, but less is known to what extent mental health problems also persist from adolescence into young adulthood. The aim of the current study was therefore to examine the chronicity and risk of mental health problems and suicidality from adolescence to young adulthood. Data stem from two Norwegian population-based studies conducted 6 years apart; the youth@hordaland study from 2012 (age 16-19) and the SHoT2018 study (age 22-25). These two data sources were linked to produce a longitudinal sample of 1257 individuals. A wide range of self-reported mental health and suicidality instruments (used both continuously and categorically) were analyzed using log-link binomial regression analysis, adjusting for age, sex, parental education, and financial problems. We found that high levels of mental health problems in late adolescence were a significant risk factor for reporting poor mental health 6 years later. Internalizing and externalizing problems in adolescence were associated with a 2.8-fold and 1.9-fold increased risk, respectively, of reporting a mental disorder 6 years later. Similarly, self-harm in adolescence was associated with a 2.1-fold increased risk of suicidal thoughts 6 years later. The magnitudes of the adjusted risk ratios were generally similar across the various mental health and suicidality measures used at the two assessment points. Adjustment for confounders did not, or only slightly, attenuate the risk ratios, and all associations remained statistically significant in the adjusted analyses. This longitudinal study provides new evidence of the chronicity of mental health problems and suicidality from adolescence to adulthood in Norway. The results emphasize the importance of early identification and timely interventions to reduce the prevalence and impact of mental health problems and suicidality.

New guidance for self-harm: an opportunity not to be missed.

In this editorial we, as members of the 2022 NICE Guideline Committee, highlight and discuss what, in our view, are the key guideline recommendations (generated through evidence synthesis and consensus) for mental health professionals when caring for people after self-harm, and we consider some of the implementation challenges.

Psychosocial factors that distinguish between men and women who have suicidal thoughts and attempt suicide: findings from a national probability sample of adults.

BACKGROUND: Previous research has highlighted the importance of understanding which psychosocial factors distinguish between those with suicide thoughts compared to those who attempt suicide. This study aims to investigate these distinguishing factors further within an ideation-to-action framework and to explore sex differences in suicide risk. METHODS: Participants (n = 7546, aged 16+) were from the cross-sectional Adult Psychiatric Morbidity Survey (APMS; 2014) of England. Face-to-face and self-completion questionnaires assessed lifetime suicidal ideation, lifetime suicide attempts, demographic characteristics, life experiences, social support, health and mental illness. Multinomial logistic regression examined factors differentiating between those with suicidal ideation only and suicide attempt histories (with or without suicidal ideation) in men and women. RESULTS: Overall men were less likely to report suicidal thoughts and attempts, compared to females. More factors differentiated between suicidal thoughts and attempts in women compared to in men; these included hospital admission for mental illness, below degree level qualifications, being single and childhood adversity. In men, factors which significantly differentiated between suicidal thoughts and attempts included self-report of professional diagnosis of mental illness and childhood adversity. Higher levels of social support were associated with being in the suicidal thoughts group v. in the attempts group in men. CONCLUSION: This study identified some key differences between men and women in factors associated with suicide attempts compared to suicidal thoughts. The findings support the use of the ideation-to-action framework to investigate sex differences in suicidal behaviour. Future research should examine the extent to which these factors are associated with suicide risk over time.

Suicide Risk in Personality Disorders: A Systematic Review.

PURPOSE OF REVIEW: This systematic review aimed to distil recent literature investigating psychosocial factors which may account for the association between personality disorder (PD) and suicide attempt or suicide death. RECENT FINDINGS: Suicide risk is particularly elevated in people with PD compared to those with no, or many other, mental health diagnoses. Despite this, suicide prevention strategies for PD populations have not progressed markedly in recent years. It is critical, therefore, to identify additional factors associated with suicide in PD populations. Of the 34 studies included in this review, most identified a relationship between personality disorder and suicide attempt and/or death. Historical interpersonal factors (e.g., childhood trauma), drug and alcohol use, and ideation-to-enaction factors were commonly associated with suicide-related outcomes. Interventions that provide interpersonal support may reduce suicide attempts. Limitations of the review include the heterogeneity of studies and small sample sizes.

Reproductive compensatory photosynthesis in a semi-arid rangeland bunchgrass.

While increased foliar photosynthesis is well documented across many plant species in response to diverse modes of herbivory, the compensatory ability of photosynthetically active reproductive structures is unknown. To address this, we partially defoliated basal florets in seed heads of crested wheatgrass (Agropyron cristatum (L.) Gaertn.), an exotic Eurasian perennial bunchgrass widely distributed across North American sagebrush steppe. We followed direct and indirect responses by tracking post-clipping photosynthesis in clipped basal and unclipped distal florets, respectively, and comparing these to similar florets on unclipped seed heads. Compensatory photosynthesis was apparent 24 h after clipping; over the pre-anthesis period, clipped basal floret photosynthesis was + 62%, stomatal conductance was + 82%, and PSII photochemical yield was - 39% of unclipped controls. After anthesis, intact florets distal to clipped florets had modestly higher photosynthetic rates compared to controls, while basal floret rates did not differ between treatments. Compensatory photosynthesis reduced intrinsic water use efficiency (iWUE; photosynthesis/stomatal conductance) 68-40% below controls over pre- and post-anthesis periods, respectively. Specific mass (dry mass/area) of clipped florets was - 15% of controls, while florets distal to these had specific mass 11% greater than distal or basal florets on unclipped seed heads. These results suggest damaged basal florets provided carbon to unaffected distal florets. This could explain crested wheatgrass's ability to produce viable seeds under conditions limiting to native bunchgrasses, and presents a novel mechanism germane to the development of convergent drought- and grazing-tolerance traits important to arid and semi-arid rangeland plant community resilience to climate variability.

Does refining an intervention based on participant feedback increase acceptability? An experimental approach.

BACKGROUND: Participant feedback is an important consideration for increasing intervention acceptability, yet whether incorporating such feedback actually improves acceptability is rarely tested. PURPOSE: The present study describes a theory-based approach to assessing whether refining an intervention based on participant feedback increases acceptability. METHODS: Three hundred and ninety-three UK adults who had previously self-harmed were exposed to the same intervention at baseline and, six months later, were randomly allocated to receive either: (a) the same version of the intervention (control group), or (b) a version of the intervention that had been refined following participant feedback (experimental group). The main outcome measure was acceptability ratings for each of the seven domains specified in the Theoretical Framework of Acceptability (TFA). RESULTS: Mixed ANOVAs, with control versus experimental group as the between-participants factor and time (baseline versus follow-up) as the within participants factor showed no significant changes in acceptability. CONCLUSIONS: The null effects reported here imply that participants found both the original and modified versions of the intervention equally acceptable, and that our process of refining an intervention based on participant feedback did not impact on acceptability. Nevertheless, we have operationalised a robust approach for examining whether participant feedback impacts on the acceptability of an intervention. Further research is required to understand better how participant feedback should be incorporated into the development of healthcare interventions.

Effects of COVID-19-related worry and rumination on mental health and loneliness during the pandemic: longitudinal analyses of adults in the UK COVID-19 mental health & wellbeing study.

BACKGROUND: The lasting effects of the coronavirus disease 2019 pandemic are likely to be significant. AIMS: This study tracked worry and rumination levels during the pandemic and investigated whether periods with higher COVID-related worry and rumination were associated with more negative mental health and loneliness. METHODS: A quota survey design and a sampling frame that permitted recruitment of a national sample were employed. Findings for waves 1 (March 2020) to 6 (November 2020) are reported (N = 1943). RESULTS: Covid-related worry and rumination levels were highest at the beginning of the first lockdown, then declined but increased when the UK returned to lockdown. Worry levels were higher than rumination levels throughout. High levels of COVID-related worry and rumination were associated with a five- and ten-fold increase in clinically meaningful rates of depression and anxiety (respectively) together with lower well-being and higher loneliness. The effects of COVID-related worry on depression and anxiety levels were most marked and clinically meaningful in individuals living with a pre-existing mental health condition. CONCLUSIONS: Psychological interventions should include components that specifically target COVID-related worry and rumination. Individuals with pre-existing mental health conditions should be prioritised as we emerge from the current pandemic and in any future public health crises.

Predicting suicidal ideation in a nationally representative sample of young adults: a 12-month prospective study.

BACKGROUND: Evidence-based theoretical models outlining the pathways to the development of suicidal ideation may inform treatment. The current research draws from the Interpersonal Theory of Suicide (IPT) and the Integrated Motivational-Volitional (IMV) Model of suicidal behaviour and aims to test the interaction between perceived burdensomeness and thwarted belongingness as proposed by the IPT model, and the defeat-entrapment pathway as proposed by the IMV model, in the prediction of suicidal ideation at 12-month follow-up. METHODS: The Scottish Wellbeing Study is a nationally representative prospective study of young people aged 18-34 years (n = 3508) from across Scotland, who completed a baseline interview and a 12-month follow-up (n = 2420). The core factors from both the IPT (perceived burdensomeness and thwarted belongingness) and the IMV model (defeat, internal and external entrapment) were measured alongside demographics, depressive symptoms and suicidal ideation at baseline. At 12-month follow-up, suicidal ideation was assessed again. RESULTS: In multiple regression analysis perceived burdensomeness and internal entrapment, with baseline suicidal ideation, predicted 12-month suicidal ideation. No support for the interaction between perceived burdensomeness and thwarted belongingness in predicting 12-month suicidal ideation was found. However, there was evidence that internal, but not external, entrapment mediated the relationship between defeat and 12-month suicidal ideation, but no support was found for the moderation of burdensomeness and belongingness on the entrapment to suicidal ideation pathway. CONCLUSIONS: The current findings highlight the importance of targeting perceived burdensomeness and internal entrapment to reduce the likelihood that suicidal ideation emerges in at risk individuals.

The association between COVID-19-related fear and reported self-harm in a national survey of people with a lifetime history of self-harm.

BACKGROUND: Relatively little is known about the characteristics of people living in the community who have previously self-harmed and may benefit from interventions during and after COVID-19. We therefore aimed to: (a) examine the relationship between reported self-harm and COVID-19-related fear, and (b) describe the characteristics of a community sample of people who reported a lifetime history of self-harm. METHODS: A cross-sectional national online survey of UK adults who reported a lifetime history of self-harm (n = 1029) was conducted. Data were collected May - June 2020. Main outcomes were self-reported COVID-19-related fear (based on the Fear of COVID-19 scale [FCV-19S]), lifetime history of COVID-19, and lifetime history of self-harm. Data were analysed using descriptive statistics and binary logistic regression. Chi-square was used to compare characteristics of our sample with available national data. RESULTS: Overall, 75.1, 40.2 and 74.3% of the total sample reported lifetime suicidal ideation, suicidal attempts and non-suicidal self-harm respectively. When adjusting for age, sex, ethnicity, social grade, and exposure to death and suicide, binary logistic regression showed higher levels of perceived symptomatic (or physiological) reactions to COVID-19 were associated with suicidal ideation (OR = 1.22, 95%CI 1.07, 1.39) and suicidal attempts (OR = 3.91, 95%CI 1.18, 12.96) in the past week. CONCLUSIONS: Results suggest an urgent need to consider the impact of COVID-19 on people with a lifetime history of self-harm when designing interventions to help support people in reducing suicidal ideation and suicidal attempts. Experiencing symptomatic reactions of fear in particular is associated with self-harm. Helping to support people to develop coping plans in response to threat-related fear is likely to help people at risk of repeat self-harm during public health emergencies.

Safety planning-type interventions for suicide prevention: meta-analysis.

BACKGROUND: Safety planning-type interventions (SPTIs) for patients at risk of suicide are often used in clinical practice, but it is unclear whether these interventions are effective. AIMS: This article reports on a meta-analysis of studies that have evaluated the effectiveness of SPTIs in reducing suicidal behaviour and ideation. METHOD: We searched Medline, EMBASE, PsycINFO, Web of Science and Scopus from their inception to 9 December 2019, for studies that compared an SPTI with a control condition and had suicidal behaviour or ideation as outcomes. Two researchers independently extracted the data. To assess suicidal behaviour, we used a random-effects model of relative risk based on a pooled measure of suicidal behaviour. For suicidal ideation, we calculated effect sizes with Hedges' g. The study was registered at PROSPERO (registration number CRD42020129185). RESULTS: Of 1816 unique abstracts screened, 6 studies with 3536 participants were eligible for analysis. The relative risk of suicidal behaviour among patients who received an SPTI compared with control was 0.570 (95% CI 0.408-0.795, P = 0.001; number needed to treat, 16). No significant effect was found for suicidal ideation. CONCLUSIONS: To our knowledge, this is the first study to report a meta-analysis on SPTIs for suicide prevention. Results support the use of SPTIs to help preventing suicidal behaviour and the inclusion of SPTIs in clinical guidelines for suicide prevention. We found no evidence for an effect of SPTIs on suicidal ideation, and other interventions may be needed for this purpose.

Mental health and well-being during the COVID-19 pandemic: longitudinal analyses of adults in the UK COVID-19 Mental Health & Wellbeing study.

BACKGROUND: The effects of coronavirus disease 2019 (COVID-19) on the population's mental health and well-being are likely to be profound and long lasting. AIMS: To investigate the trajectory of mental health and well-being during the first 6 weeks of lockdown in adults in the UK. METHOD: A quota survey design and a sampling frame that permitted recruitment of a national sample was employed. Findings for waves 1 (31 March to 9 April 2020), 2 (10 April to 27 April 2020) and 3 (28 April to 11 May 2020) are reported here. A range of mental health factors was assessed: pre-existing mental health problems, suicide attempts and self-harm, suicidal ideation, depression, anxiety, defeat, entrapment, mental well-being and loneliness. RESULTS: A total of 3077 adults in the UK completed the survey at wave 1. Suicidal ideation increased over time. Symptoms of anxiety, and levels of defeat and entrapment decreased across waves whereas levels of depressive symptoms did not change significantly. Positive well-being also increased. Levels of loneliness did not change significantly over waves. Subgroup analyses showed that women, young people (18-29 years), those from more socially disadvantaged backgrounds and those with pre-existing mental health problems have worse mental health outcomes during the pandemic across most factors. CONCLUSIONS: The mental health and well-being of the UK adult population appears to have been affected in the initial phase of the COVID-19 pandemic. The increasing rates of suicidal thoughts across waves, especially among young adults, are concerning.

Distinguishing prisoners who think about suicide from those who attempt suicide.

BACKGROUND: Many people who consider suicide do not translate these intentions into action. Although prisoners constitute a particularly high-risk group for suicide, little is known about the factors that distinguish those who think about suicide from those who attempt suicide. METHODS: Participants were 1326 adult offenders (1203 men) randomly selected from 15 Belgian prisons, representing 14% of the national prison population. Multivariate regression analysis compared prisoners who attempted suicide (n = 277) with those who thought about suicide but never made an attempt (n = 312) on a range of established risk factors. RESULTS: Among the 589 participants reporting a lifetime history of suicidal ideation (44% of the total sample), almost half (47%) had made a suicide attempt. Relative to those who only thought about suicide, participants who attempted suicide were more likely to be violent offenders (aOR 2.33, 95% CI 1.49-3.62) and have a history of non-suicidal self-injury (aOR 3.19, 95% CI 2.09-4.86). The presence of self-reported mental disorder diagnosis (aOR = 2.84, 95% CI 1.91-4.24) and illicit substance abuse (aOR = 2.01, 95% CI 1.24-3.28) also independently differentiated prisoners who attempted v. considered suicide. CONCLUSION: This study provides preliminary evidence that behavioural and mental health factors are implicated in the transition from thoughts to acts of suicide in prisoners. Prospective studies are warranted to explore whether these risk factors predict progression from ideation to action over time.

Using the integrated motivational-volitional (IMV) model of suicidal behaviour to differentiate those with and without suicidal intent in hospital treated self-harm.

Self-harm is a major public health concern. In order to respond to self-harm effectively, it is important to understand the factors associated with self-harm with and without suicidal intent. To this end, we investigated psychological factors selected from the Integrated Motivational-Volitional (IMV) model of suicidal behaviour in individuals who had recently been admitted to hospital for self-harm, with the aim of examining the characteristics of those who expressed intent to die versus those without suicidal intent. Individuals (n = 500, 60.6% female) admitted to two hospitals in central Scotland following self-harm with (suicide attempt [SA] group, n = 336) or without (non-suicidal self-harm [NSSH] group, n = 164) suicidal intent completed a range of psychological measures. Over half of the participants reported previous episodes of self-harm (SA, n = 239, 71.1%; NSSH, n = 91, 55.5%). Univariate analyses revealed that the SA and NSSH groups differed on some of the psychological measures with higher depressive symptoms, defeat, entrapment, acquired capability and impulsivity in the SA compared to the NSSH group. In the multivariate model, suicidal ideation, defeat, internal entrapment and perceived burdensomeness independently differentiated between the groups. These findings highlight the complex profiles of individuals presenting at hospital with self-harm and emphasise the need to investigate differences between subtypes of self-harm in order to support individuals optimally. Applying frameworks such as the IMV model to further understanding of self-harm might assist in the development of targeted psychological interventions to reduce risk of repeat self-harm or suicide.

The impact on mental health practitioners of the death of a patient by suicide: A systematic review.

There is a growing body of research investigating the impact on mental health professionals of losing a patient through suicide. However, the nature and extent of the impact is unclear. This systematic review synthesizes both quantitative and qualitative studies in the area. The aim was to review the literature on the impact of losing a patient through suicide with respect to both personal and professional practice responses as well as the support received. A search of the major psychological and medical databases was conducted, using keywords including suicide, patient, practitioner, and impact, which yielded 3,942 records. Fifty-four studies were included in the final narrative synthesis. Most common personal reactions in qualitative studies included guilt, shock, sadness, anger, and blame. Impact on professional practice included self-doubt and being more cautious and defensive in the management of suicide risk. As quantitative study methodologies were heterogeneous, it was difficult to make direct comparisons across studies. However, 13 studies (total n = 717 practitioners) utilized the Impact of Event Scale, finding that between 12% and 53% of practitioners recorded clinically significant scores. The need for training that is focused on the impact of suicides, and the value placed upon informal support was often cited. The experience of losing a patient through suicide can have a significant impact on mental health professionals, both in terms of their personal reactions and subsequent changes to professional practice. The negative impact, however, may be moderated by cultural and organisational factors and by the nature of support available.

Understanding and managing suicide risk.

BACKGROUND: Suicidal behaviours and non-suicidal self-harm (NSSH) are global public health concerns that affect millions of lives. SOURCES OF DATA: This review is a narrative synthesis of systematic reviews, meta-analyses of randomized control trials (RCTs) and landmark studies published in scientific journals. AREAS OF AGREEMENT: Restricting access to lethal means reduces the likelihood of future suicide deaths. AREAS OF CONTROVERSY: Our ability to predict future suicidal behaviour is no better than chance. No individual risk prediction instrument offers sufficient sensitivity and specificity to inform clinically useful decision-making. GROWING POINTS: Different types of psychosocial interventions may be effective in preventing future suicide attempts; such interventions include clinical assessment, tailored crisis response and safety plans and follow-up contact. AREAS TIMELY FOR DEVELOPING RESEARCH: Whilst some psychosocial interventions can be effective in reducing suicide risk, little is known about the mechanisms of recovery from suicidal thoughts and behaviours.

The scope of mental health research during the COVID-19 pandemic and its aftermath.

The effects of the COVID-19 pandemic on population mental health are unknown. We need to understand the scale of any such impact in different sections of the population, who is most affected and how best to mitigate, prevent and treat any excess morbidity. We propose a coordinated and interdisciplinary mental health science response.

What distinguishes adolescents with suicidal thoughts from those who have attempted suicide? A population-based birth cohort study.

BACKGROUND: Only one-third of young people who experience suicidal ideation attempt suicide. It is important to identify factors which differentiate those who attempt suicide from those who experience suicidal ideation but do not act on these thoughts. METHODS: Participants were 4,772 members of the Avon Longitudinal Study of Parents and Children (ALSPAC), a UK population-based birth cohort. Suicide ideation and attempts were assessed at age 16 years via self-report questionnaire. Multinomial regression was used to examine associations between factors that differentiated adolescents in three groups: no suicidal ideation or attempts, suicidal ideation only and suicide attempts. Analyses were conducted on an imputed data set based on those with complete outcome data (suicidal thoughts and attempts) at age 16 years (N = 4,772). RESULTS: The lifetime prevalence of suicidal ideation and attempts in the sample was 9.6% and 6.8% respectively. Compared to adolescents who had experienced suicidal ideation, those who attempted suicide were more likely to report exposure to self-harm in others (adjusted OR for family member self-harm: 1.95, for friend self-harm: 2.61 and for both family and friend self-harm: 5.26). They were also more likely to have a psychiatric disorder (adjusted OR for depression: 3.63; adjusted OR for anxiety disorder: 2.20; adjusted OR for behavioural disorder: 2.90). Other risk factors included female gender, lower IQ, higher impulsivity, higher intensity seeking, lower conscientiousness, a greater number of life events, body dissatisfaction, hopelessness, smoking and illicit drug use (excluding cannabis). CONCLUSIONS: The extent of exposure to self-harm in others and the presence of psychiatric disorder most clearly differentiate adolescents who attempt suicide from those who only experience suicidal ideation. Further longitudinal research is needed to explore whether these risk factors predict progression from suicidal ideation to attempts over time.

Differentiating adults who think about self-harm from those who engage in self-harm: the role of volitional alcohol factors.

BACKGROUND: Self-harm, an act of self-poisoning or self-injury irrespective of motivation, is a major public health concern. Use of alcohol prior to or alongside acts of self-harm is common but little is known about the alcohol-related mechanisms of self-harm enaction. We utilised an ideation-to-action approach to clarify the extent to which volitional alcohol factors differentiated those who have thoughts of self-harm but do not act on them (self-harm ideation) and those who engage in self-harm (self-harm enaction). METHODS: Cross-sectional analyses of the baseline phase of the Health Lifestyle and Wellbeing study: 1546 adults (1079 female; Mean age = 34 y; 92% White) resident in Scotland completed measures of demographics, lifetime self-harm, volitional alcohol factors and psychosocial factors. Multinomial logistic regression compared those with a history of self-harm thoughts ('ideation', n = 297), self-harm acts ('enaction', n = 346) and 'controls' (n = 897) to identify volitional alcohol factors associated with self-harm enaction. RESULTS: Volitional alcohol factors differentiated those with a history of self-harm enaction from those with a history of self-harm ideation (as well as those with no history) in initial models adjusted for demographics and depressive symptoms: the self-harm enaction group reported stronger alcohol-related negative urgency (OR = 1.74, 95% CI 1.41-2.16, p < .001), more frequent heavy drinking (OR = 1.46, 95% CI 1.24-1.72, p < .001) and stronger expectancies that drinking alcohol leads to negative self-perceptions (OR = 1.33, 95% CI 1.03-1.72, p = 0.03) and markers of self-harm risk (OR = 1.64, 95% CI 1.18-2.30, p = 0.004). Alcohol-related negative urgency and heavy-drinking frequency continued to differentiate those in the self-harm enaction group from those in ideation group in multivariate models. Consistent with theoretical models positing phase-specific moderators of self-harm ideation and enaction, psychosocial factors (perceived stress, support, negative mood regulation expectancies) differentiated those with a history of self-harm ideation from those without but not those in the ideation and enaction groups. CONCLUSIONS: Management of self-harm risk requires better understanding of alcohol-related mechanisms of self-harm enaction. Volitional alcohol factors may play a role in governing the translation of self-harm thoughts into self-harm acts.

The role of physical and mental multimorbidity in suicidal thoughts and behaviours in a Scottish population cohort study.

BACKGROUND: Physical illness and mental disorders play a significant role in fatal and non-fatal suicidal behaviour. However, there is no clear evidence for the effect of physical and mental illness co-occurrence (multimorbidity) in suicidal ideation and attempts. The aim of the current study was to investigate, whether physical/mental health multimorbidity predicted suicidal thoughts and behaviours as outcomes. METHODS: Data from the West of Scotland Twenty-07 cohort were analysed. Twenty-07 is a multiple cohort study following people for 20 years, through five waves of data collection. Participants who responded to past-year suicidal thoughts and suicide attempt items were grouped into four distinct health-groups based on having: (1) neither physical nor mental health condition (controls); (2) one or more physical health condition; (3) one or more mental health condition and; (4) multimorbidity. The role of multimorbidity in predicting suicidal ideation and suicide attempts was tested with a generalised estimating equation (GEE) model and odds ratios (ORs) and 95% CIs are presented. Whether the effect of multimorbidity was stronger than either health condition alone was also assessed. RESULTS: Multimorbidity had a significant effect on suicidal thoughts and suicide attempts, compared to the control group, but was not found to increase the risk of either suicide-related outcomes, more than mental illness alone. CONCLUSIONS: We identified an effect of physical/mental multimorbidity on risk of suicidal thoughts and suicide attempts. Considering that suicide and related behaviour are rare events, future studies should employ a prospective design on the role of multimorbidity in suicidality, employing larger datasets.

Adult attachment: Investigating the factor structure of the Relationship Scales Questionnaire.

OBJECTIVE: In this study, we aimed to conduct an in-depth psychometric investigation of the Relationships Scales Questionnaire (RSQ). METHOD: About 717 UK-based participants responded to an online questionnaire (F = 540, M = 177; age range 18-66 years, M = 25, SD = 8.46). We conducted (a) a series of confirmatory factor analyses (CFA) to test previously published factor models of the RSQ, (b) traditional (exploratory factor analysis and confirmatory factor analysis) and contemporary (exploratory graph analysis) exploratory techniques, followed by (c) validity and reliability analyses. RESULTS: Although the RSQ was developed to assess four categories of adult attachment (typological approach - i.e., secure, preoccupied, dismissing, and fearful), our findings do not support the hypothesis that the RSQ delivers a psychometrically consistent measure of adult attachment styles. CONCLUSION: The results of the present study suggest that a two-dimensional approach (i.e., anxiety and avoidance) to assessing adult attachment is optimal.
