Intervention Summary

Lifelines Curriculum

Lifelines is a comprehensive, schoolwide suicide prevention program for middle and high school students. The goal of Lifelines is to promote a caring, competent school community in which help seeking is encouraged and modeled and suicidal behavior is recognized as an issue that cannot be kept secret. Lifelines seeks to increase the likelihood that school staff and students will know how to identify at-risk youth when they encounter them, provide an appropriate initial response, and obtain help, as well as be inclined to take such action.

Lifelines includes a set of components to be implemented sequentially: a review of resources and establishment of administrative guidelines and procedures for responding to a student at risk; training for school faculty and staff to enhance suicide awareness and an understanding of the role they can play in identifying and responding to a student with suicidal behavior; a workshop and informational materials for parents; and implementation of a curriculum for students, the Lifelines Curriculum, to inform students about suicidal behavior and discuss their role in suicide prevention.

The research reviewed for this summary assessed only the Lifelines Curriculum, the last component to be implemented in the larger Lifelines program. It consists of four 45-minute or two 90-minute lessons that incorporate elements of the social development model and employ interactive teaching techniques, including role-play. Health teachers and/or guidance counselors teach the lessons within the regular school health curriculum. The Lifelines Curriculum was developed specifically for students in grades 8-10 but can be used with students through 12th grade.

Implementation History Lifelines has been most widely used in Maine but is now being implemented in other States. Early versions of Lifelines were implemented in New Jersey, with the first evaluated version being implemented. A subsequent evaluation was conducted in Maine. The Maine Youth Suicide Prevention Program (MYSPP) has been providing Lifelines teacher training in the State, an estimated 33 schools were implementing the curriculum. Twenty-nine schools in Maine have been funded by Federal grants to implement and evaluate the comprehensive program.

Documents Reviewed

The documents below were reviewed for Quality of Research. The research point of contact can provide information regarding the studies reviewed and the availability of additional materials, including those from more recent studies that may have been conducted.

Outcomes

Outcome 1: Knowledge about suicide
Description of Measures Knowledge about suicide, including facts and myths about suicide and persons at risk for suicide, was measured using 8 true/false items from the Lifelines Student Questionnaire. Sample items on this self-administered questionnaire include "People who talk about suicide do not commit suicide," "Most teens who try to kill themselves really want to die," and "Suicide attempts are rare among good students."
Key Findings The intervention group demonstrated a significantly greater increase in knowledge about suicide from pretest to 2 weeks postintervention than the control group, which received physical education classes during the study and participated in Lifelines after the study (p < .001).
Studies Measuring Outcome Study 1
Study Designs Quasi-experimental
Quality of Research Rating 2.9 (0.0-4.0 scale)
Outcome 2: Attitudes about suicide and suicide intervention
Description of Measures Attitudes about suicide and suicide intervention were measured using 6 questions from the Lifelines Student Questionnaire. Sample items on this self-administered questionnaire include "Teens can't do very much to prevent teen suicide," "If somebody wants to kill themselves, nobody has the right to stop them," and "If a friend began to lose interest in activities and friends and sometimes said things like s(he) wasn't much good to anyone, would you mind your own business and let him/her have his/her privacy?" All items use a 4-point Likert scale from "strongly agree" to "strongly disagree" or "definitely would" to "definitely would not." Favorable attitudes reflect the belief that suicide is not inevitable, the belief that it is appropriate to intervene with a person at risk, and a willingness to intervene.
Key Findings The intervention group demonstrated significantly greater improvement in attitudes about suicide and suicide intervention from pretest to 2 weeks postintervention than the control group, which received physical education classes during the study and participated in Lifelines after the study (p < .001).

Outcome 3: Attitudes about seeking adult help
Description of Measures Attitudes about seeking adult help were measured using 6 questions from the Lifelines Student Questionnaire. Sample items on this self-administered questionnaire include "It is important to have at least one adult that you can talk to if something is bothering you," "My school is prepared to help a student who might be thinking about killing him/herself," and "If a friend told you that s(he) was thinking about killing him/herself, would you talk to an adult about him/her?" All items use a 4-point Likert scale from "strongly agree" to "strongly disagree" or "definitely would" to "definitely would not." Favorable attitudes reflect the belief that it is important to seek adult help, the belief that there is an adult in whom the respondent could confide, the belief that the school is prepared to respond to a student at risk, and a willingness to seek adult help when someone (either self or a friend) is distressed or demonstrating signs of suicidal risk.
Key Findings The intervention group demonstrated significantly greater improvement in attitudes about seeking adult help from pretest to 2 weeks postintervention than the control group, which received physical education classes during the study and participated in Lifelines after the study (p < .001).

Outcome 4: Attitudes about keeping a friend's suicide thoughts a secret
Description of Measures Attitudes about keeping a friend's suicide thoughts a secret were measured using 6 items on the Lifelines Student Questionnaire. Sample items from this self-administered questionnaire include "A friend's confidence about suicidal feelings should never be broken," "I would try to help a suicidal friend without getting help from someone else," and "If a friend told you s(he) was thinking about killing him/herself, would you respect his/her privacy and keep it a secret?" All items use a 4-point Likert scale from "strongly agree" to "strongly disagree," "definitely would" to "definitely would not," or "definitely tell someone" to "definitely not tell someone." Favorable attitudes reflect the belief that it is appropriate to break a friend's confidence if the friend is at risk of suicide and a willingness to share a friend's secret with someone who could help.
Key Findings The intervention group demonstrated significantly greater improvement in attitudes about keeping a friend's suicide thoughts a secret from pretest to 2 weeks postintervention than the control group, which received physical education classes during the study and participated in Lifelines after the study (p < .001).

Dissemination Strengths

Program materials provide guidance to multiple audiences involved in the implementation of the program, including school district administrators, teachers, parents, and students. The program curriculum is comprehensive and easy to understand, and materials are supplemented by detailed sample organizational policies to support the success of the intervention. Training and consultation are available from the developer at on- and off-site locations. A train-the-trainer component can be used to minimize extended training costs. Multiple tools are provided to support implementation fidelity. A student questionnaire for assessing participant change in knowledge and attitudes can be used to support quality assurance.

Dissemination Weaknesses

No mechanism is in place for school districts implementing the program to network with each other to continually develop and improve the model or to share problems encountered and lessons learned during implementation. Other than through consultation with the developer, implementers are not given any guidance on how to measure the impact of the program within a school or school district.

Costs
