Addressing help-seeking, stigma and risk factors for suicidality in secondary schools: short-term and mid-term effects of the HEYLiFE suicide prevention program in a randomized controlled trial

BACKGROUND

Suicidal ideation and suicide attempts present a serious public health concern among adolescents and young adults. School-based suicide prevention programs are a key tool for addressing this problem. However, more research is necessary to assess their effectiveness, acceptability, and safety. In response, the HEYLiFE suicide prevention program was developed to enhance help-seeking, reduce stigma towards suicidal peers and diminish risk factors for suicidality. This article presents the evaluation findings of the HEYLiFE program in German secondary schools.

METHODS

We conducted a randomized-controlled trial measuring short-term pre-post within-group effects in the intervention group only and mid-term effects at 6-months-follow-up compared to a waitlist-control group. Schools were assigned randomly to the intervention or control group (no blinding). We recruited students ≥12 years of age. Primary outcomes were knowledge about suicidality, attitudes towards suicidality, stigma towards a suicidal peer, help-seeking intentions and behaviours, risk factors for suicidality. The data was analysed with linear mixed models and generalized linear mixed models.

RESULTS

A total of N = 745 students participated (n = 353 intervention group, n = 392 control group). We observed favourable short-term effects on knowledge, attitudes towards suicidality and fear towards a suicidal peer. Unexpectedly, the program also led to an increase in desire for social distance and a decrease in prosocial emotions towards a suicidal peer. The mid-term effects of the program were exclusively favourable, resulting in enhanced attitudes towards help-seeking while protecting from a sharper rise in risk-factors for suicidality and from an increase in social distance. The program had more favourable effects on females and on students aged >13 years. The program was well-received by the students, and no serious adverse events were reported.

CONCLUSIONS

These findings demonstrate the effectiveness of the HEYLiFE universal suicide prevention program in addressing variables associated with suicidal ideation and suicide attempts among adolescents on the mid-term. The short-term negative effects on stigma and more negative effects on males should be addressed in the future. Future evaluation studies should examine its effects on suicidality and its effectiveness within populations at high risk.

TRIAL REGISTRATION

The study was preregistered in the German Clinical Trials Register (registration number: DRKS00017045; registration date: 02/04/2019).

Sexual and contraceptive behaviour of young adults in Germany - Results from KiGGS Wave 2

Sexual behaviour is an important aspect of sexual health. 18-year-old and older participants of the KiGGS cohort in KiGGS Wave 2 were asked about their sexual and contraceptive behaviour. Data from 2,966 women and 2,206 men were included in the analysis, which was adjusted to the age and sex distribution of the German population by means of weighting. More than half of the respondents report their first sexual intercourse before reaching the age of majority (women 61%, men 53%). Women report a lower age than men. With regard to the number of opposite-sex sexual partners in the last twelve months, almost 69% of women and 58% of men state that they have had contact. Three or more sexual partners were reported by 11% of women and 20% of men. 7.4% of women have same-sex and 1.4% have both same-sex and opposite-sex sexual contacts, among men the figures are 2.8% and 0.4%, respectively. When asked about the type of contraception used during the last sexual intercourse, about two thirds of the women and more than half of the men indicated the pill; a condom is used by about 44% of the women and about two thirds of the men. Almost one third of the women have already taken the morning-after pill. Overall, the results can help to support prevention and education campaigns on sexual and reproductive health.
