- The aim of the study was to ascertain suicide seasonality in the Greek population and to associate this seasonal variation with age, sex, and suicide method. Studying seasonality can be of help in establishing a public health policy, related with suicide prevention. This is an epidemiologic study based on forensic evidence. We studied the deaths caused by self-injury (trauma), namely deaths by violent suicide (not self-poisoning). Statistically significant suicide seasonality was established with a peak in May. This seasonal variation is attributed mainly to males. As for the method, suicide by hanging peaks in June and by shooting in April. It was also observed that seasonality for individuals above the age of 45 peaks in early May.

- Objective To investigate suicide ideation and behavior as risk factors for suicide in schizophrenia during varying time periods. Method Cases were 84 patients who died by suicide within 5 years from diagnosis in a source population of patients discharged for the first time from psychiatric hospitals in Stockholm County, Sweden, with a schizophrenia spectrum diagnosis. One control was individually matched with each suicide case. Data were retrieved from clinical records in a blind fashion. Thoughts of death, thoughts of suicide, suicide plan, and suicide attempt during varying time periods were investigated as risk factors for subsequent completed suicide. Results In adjusted analyses, thoughts of suicide, suicide plan, and suicide attempt were significantly associated with subsequent completed suicide in the following year. The highest suicide risk was found within a year following suicide attempt (adjusted OR 9.9, 95% confidence interval 2.5-39.0). The association between suicide ideation and behavior and subsequent suicide declined over time. Conclusions Several types of suicide ideation and behavior were associated with suicide, and the association was stronger for suicidal behavior. The clinical significance of suicidal communication appears highest during the following month or/and year. Many suicides occurred without recorded short-term suicidal communication.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The Imaginator study tested the feasibility of a short mental imagery‐based psychological intervention for young people who self‐harm and used a stepped‐wedge design to investigate effects on self‐harm frequency reduction at 3 and 6 months.Method: A total of 38 participants aged 16–25 were recruited via community self‐referral and mental health services. Participants were randomized to immediate delivery of Functional Imagery Training (FIT) or usual care followed by delayed delivery after 3 months. FIT comprised two face‐to‐face sessions, five phone sessions, and use of a smartphone app. Outcomes’ assessment was blind to allocation.Results: Three quarters of those who began treatment completed face‐to‐face sessions, and 57% completed five or more sessions in total. Self‐harm frequency data were obtained on 76% of the sample at 3 months (primary outcome) and 63% at 6 months. FIT produced moderate reductions in self‐harm frequency at 3 months after immediate (d = 0.65) and delayed delivery (d = 0.75). The Immediate FIT group maintained improvements from 3 to 6 months (d = 0.05). Participants receiving usual care also reduced self‐harm (d = 0.47).Conclusions: A brief mental imagery‐based psychological intervention targeting self‐harm in young people is feasible and may comprise a novel transdiagnostic treatment for self‐harm.

Genetic differences between suicide deaths and deaths of undetermined intent
- 2023
-
Ingår i: Suicide and Life-Threatening Behavior. - : Wiley. - 0363-0234 .- 1943-278X. ; 53:1, s. 100-109
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: Few, if any, prior studies have considered whether undetermined intent (UDI) deaths and suicide deaths differ with respect to genetic liability for suicidal behavior or psychopathology. Methods: The authors used Swedish national registry data to identify suicide deaths (N = 31,835) and UDI deaths (N = 10,623); sociodemographic covariates; and registrations for psychopathology. Family genetic risk scores (FGRS) were derived for each form of psychopathology. The authors used LASSO models to assess genetic and phenotypic differences across outcomes. Results: In the multivariate LASSO regressions, higher FGRS for major depression, bipolar disorder, and suicide death were associated with lower odds of UDI relative to unambiguous suicide (OR = 0.91–0.95), while those for alcohol and drug use disorders, ADHD, and criminal behavior were associated with higher odds of UDI relative to unambiguous suicide (OR = 1.04–1.12). When the corresponding phenotypic registration status for these outcomes was included in a subsequent model, the associations were attenuated and of small magnitude, but many remained different from OR = 1. Conclusions: Aggregate genetic differences between unambiguous suicide decedents and UDI deaths are small, particularly when accounting for psychiatric comorbidity, but in some cases, statistically significant. These findings suggest that different analytic treatment of UDI deaths may be warranted depending on the research question. Replication in other samples, and using molecular genetic data, is necessary.

Tidskriftsartikel (refereegranskat)abstract
- Different methods of poisoning used by individuals with the diagnosis of parasuicide admitted to the Loghman Hospital, Tehran, from 2000 to 2004 were investigated, with particular focus on gender and age differences. Drugs, pesticides, and other agricultural chemicals (women: 12.7%, men: 9%) were the most commonly used methods. In males, the percentage of use of drugs increased with age, but the frequency of pesticides use decreased with age. In females, drugs were most often used in the youngest age group, whereas the use of pesticides was lowest in the youngest age category. Females outnumbered males, especially in the youngest age group of 10 to 19 years olds. Drugs and pesticides were the substances used most often for parasuicide in each age group regardless of gender.

Tidskriftsartikel (refereegranskat)abstract
- Mental disorders in the general population are associated with increased risk of suicidality, but less is known about the independent predictive ability of self-reported psychological symptoms. We followed 49,321 screened and interviewed Swedish conscripts through 36-year follow-up to test whether psychological symptoms predicted suicide and hospitalization for suicide attempts. There were 619 suicides and 1,230 suicide attempts during the follow-up period. After excluding subjects with any psychiatric diagnoses (n=5,691, 12%) and controlling for other psychological symptoms, severe symptoms of anger, trouble falling asleep, and feeling down predicted suicide. Similarly anger, headaches, feeling down, and nervousness predicted suicide attempt. Self-reported psychological symptoms may have a predictive value beyond psychiatric diagnosis.

Similarities and Differences in the Functions of Nonsuicidal Self-Injury (NSSI) and Sex as Self-Injury (SASI)
- 2019
-

Tidskriftsartikel (refereegranskat)abstract
- Differences and similarities were studied in the functions of two different self-injurious behaviors (SIB): nonsuicidal self-injury (NSSI) and sex as self-injury (SASI). Based on type of SIB reported, adolescents were classified in one of three groups: NSSI only (n=910), SASI only (n=41), and both NSSI and SASI (n=76). There was support for functional equivalence in the two forms of SIB, with automatic functions being most commonly endorsed in all three groups. There were also functional differences, with adolescents in the SASI only group reporting more social influence functions than those with NSSI only. Adolescents reporting both NSSI and SASI endorsed the highest number of functions for both behaviors. Clinical implications are discussed, emphasizing the need for emotion regulation skills.

Per Capita Alcohol Consumption and Suicide Rates in the U.S., 1950–2002
- 2009
-
Ingår i: Journal of Suicide and Life-threatening Behaviour. - : Wiley. - 0363-0234 .- 1943-278X. ; 38:4, s. 452-459
-
Tidskriftsartikel (refereegranskat)abstract
- The aim of this paper was to estimate how suicide rates in the United States are affected by changes in per capita consumption during the postwar period. The analysis included Annual suicide rates and per capita alcohol consumption data (total and beverage specific) for the period 1950–2002. Gender- and age-specific models were estimated using the Box-Jenkins technique for time series analysis. No significant estimate was found for males. For females the total alcohol estimate (0.059) was significant at the 10% level whereas the spirits estimate was significant with an effect of 0.152. The results imply that a change in U.S. per capita consumption would result in a change in female suicide rates, whereas the male rates would not be affected.

-
Ingår i: Suicide and Life-Threatening Behavior. - : Wiley. - 0363-0234 .- 1943-278X. ; 52:2, s. 341-351

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Alcohol use disorder (AUD) has been identified as a strong risk factor for suicide attempt. However, few studies have considered protective factors that may moderate this association, such as resilience. Methods: We used longitudinal nationwide Swedish data of 903,333 males born 1960–1980 and 48,285 males born 1949–1951. We performed Cox proportional hazards models to test the role of AUD, resilience, and their interaction on risk for suicide attempt. We used co-relative models to account for familial factors. Results: Alcohol use disorder was strongly associated with increased risk of suicide attempt [hazard ratio (HR) = 12.22], while resilience was associated with reduced risk (HR = 0.73). Multiplicative interaction (HR = 1.21) showed that, in the context of AUD, the protective role of resilience on risk of suicide attempt was somewhat attenuated. Co-relative analyses supported both familial liability and a possible causal pathway between AUD, resilience, and suicide attempt. In the cohort born 1949–1951, resilience subcomponents—social maturity, interests, psychological energy, home conditions, and emotional control—were all associated with reduced suicide attempt risk (HRs between 0.63 and 0.74). Conclusion: While resilience is associated with reduced risk of suicide attempt, this effect is less pronounced in the context of AUD. These associations are potentially causal.

- Encountering the body of a child who died by suicide at the site of death is believed to be especially harmful for bereaved parents. We investigated the association between encountering the body at the site of the suicide and psychological distress in 666 suicide-bereaved parents. Parents who had encountered their child's body at the site of the suicide (n = 147) did not have a higher risk of nightmares (relative risk [RR] 0.95, 95% confidence interval [CI] 0.67-1.35), intrusive memories (RR 0.97, 95% CI 0.84-1.13), avoidance of thoughts (RR 0.97, 95% CI 0.74-1.27), avoidance of places or things (RR 0.91, 95% CI 0.66-1.25), anxiety (RR 0.93, 95% CI 0.64-1.33), or depression (RR 0.94, 95% CI 0.63-1.42) compared with parents who had not encountered the body (n = 512). Our results suggest that losing a child by suicide is sufficiently disastrous by itself to elicit posttraumatic responses or psychiatric morbidity whether or not the parent has encountered the deceased child at the site of death.

- Our aim was to build a model delineating the relationship between attitudes toward suicide and suicidal behavior and to assess equivalence by applying the model on data from different countries. Representative samples from the general population were approached in Sweden, Norway, and Russia with the Attitudes Toward Suicide (ATTS) questionnaire. Data on experience of suicidal behavior among significant others and self-reported suicidal expressions were also collected. Structural equation modeling resulted in gender and country specific models where experience of suicidal behavior among significant others and self-reported suicidal expressions earlier in life predicted attitudes, and attitudes predicted current suicidal expressions. The models included the attitude factors acceptance of suicide, condemnation, and preventability; age and level of education were also incorporated. The different models reveal possible ways to better understand gender and culture-specific paths between attitudes and suicidal behaviors, and their relevance in a suicide prevention context is considered.

- An instrument measuring attitudes toward suicide was developed through two postal questionnaire surveys, 1986 and 1996, approaching general population samples of 700 and 1,000 persons, respectively, and with response rates of 75% and 64%. A 10-factor model was obtained and comparisons between waves revealed an overall more permissive and pro-preventional attitude in 1996. The results implied complex relationships at the aggregated level between attitudes and suicidal behavior, depending on type of suicidal behavior, attitude factor, and subgroup. At the individual level, persons answering affirmative on own suicidal behavior, as compared to the nonsuicidal group, held a more permissive and understanding attitude toward suicide.

Tidskriftsartikel (refereegranskat)abstract
- Nonsuicidal self-injury disorder (NSSID) is a condition in need of further study to assess the validity of the potential diagnosis and its suggested criteria. This study examined the NSSID diagnosis and investigated the distress/impairment criterion by comparing community adolescents who met all criteria for NSSID (n = 186) to adolescents with five or more nonsuicidal self-injury (NSSI) episodes (n = 314), and to a group of adolescents who met all criteria but negated that their NSSI caused them any distress or impairment, thus failing to meet criterion E (n = 29). The NSSID group delimited from the ≥ 5 NSSI group by reporting significantly more frequent and severe self-injurious thoughts and behaviors, as well as having more experiences of negative life events and higher levels of trauma symptoms. There were also some differences between the NSSID group and adolescents without distress/impairment, which together contribute valuable information on the potential NSSID diagnosis, as well as the discussion of criterion E.
