The Psychosocial Universal Lens for Screening and Early Support (PULSE) System

Background

PULSE was devel­oped as a brief uni­ver­sal men­tal health screen­ing, progress mon­i­tor­ing, and school func­tion­ing sur­veil­lance sys­tem derived from the Ear­ly Iden­ti­fi­ca­tion Sys­tem (EIS). The goal was to pre­serve the mul­ti­di­men­sion­al struc­ture, the­o­ret­i­cal foun­da­tion, and psy­cho­me­t­ric rig­or of the EIS while sub­stan­tial­ly reduc­ing admin­is­tra­tion bur­den and increas­ing fea­si­bil­i­ty for large-scale implementation.

Conceptual Foundation

PULSE is ground­ed in pre­ven­tion sci­ence and a pub­lic health approach to edu­ca­tion. Rather than func­tion­ing sole­ly as a men­tal health screen­er, PULSE serves as a sur­veil­lance sys­tem for mon­i­tor­ing stu­dent well­be­ing and the con­di­tions that sup­port healthy devel­op­ment in schools. The sys­tem reflects the premise that aca­d­e­m­ic, behav­ioral, emo­tion­al, and social func­tion­ing are inter­con­nect­ed indi­ca­tors of stu­dent well­be­ing and edu­ca­tion­al success.

Primary Uses

• Uni­ver­sal screen­ing of psy­choso­cial risk
• Ear­ly iden­ti­fi­ca­tion of stu­dents need­ing support
• Progress mon­i­tor­ing of stu­dent wellbeing
• School­wide sur­veil­lance of men­tal health and school functioning
• Eval­u­a­tion of pre­ven­tion and inter­ven­tion efforts
• Data-informed deci­sion mak­ing with­in MTSS

Measure Structure

Stu­dent Self-Report assess­es: Atten­tion and Aca­d­e­m­ic Issues, Bul­ly Behav­iors, Dis­en­gage­ment, Emo­tion Dys­reg­u­la­tion, Inter­nal­iz­ing Prob­lems, Peer Rela­tion­ship Prob­lems, and School Safe­ty Concerns.

Teacher Report assess­es: Atten­tion and Aca­d­e­m­ic Issues, Bul­ly Behav­iors, Emo­tion Dys­reg­u­la­tion, Exter­nal­iz­ing Behav­ior, Inter­nal­iz­ing Prob­lems, and Peer Rela­tion­ship Problems.

Development Process

PULSE was devel­oped using an IRT-informed, the­o­ry-dri­ven item reduc­tion process. Sep­a­rate mul­ti­di­men­sion­al item response the­o­ry analy­ses were con­duct­ed for stu­dent and teacher forms. Item selec­tion incor­po­rat­ed dis­crim­i­na­tion para­me­ters, cov­er­age across the latent con­tin­u­um, dif­fer­en­tial item func­tion­ing analy­ses, local depen­dence analy­ses, and expert review. The result­ing item sets were select­ed to max­i­mize effi­cien­cy while main­tain­ing con­struct cov­er­age and risk detec­tion capability.

Psychometric Findings

Analy­ses sup­port­ed the mul­ti­di­men­sion­al struc­ture of both forms. Stu­dent-report and teacher-report mod­els demon­strat­ed strong over­all fit, accept­able item func­tion­ing, min­i­mal dif­fer­en­tial item func­tion­ing across demo­graph­ic groups, and strong dis­crim­i­na­tion char­ac­ter­is­tics. Retained items pro­vid­ed cov­er­age across the range of psy­choso­cial risk most rel­e­vant for uni­ver­sal screen­ing and prevention.

Progress Monitoring and Surveillance

Unlike many tra­di­tion­al school men­tal health screen­ers, PULSE was designed to sup­port repeat­ed admin­is­tra­tion. Schools can mon­i­tor changes in stu­dent well­be­ing, eval­u­ate inter­ven­tion effec­tive­ness, iden­ti­fy emerg­ing con­cerns, and track indi­ca­tors of school func­tion­ing over time. This sur­veil­lance approach enables con­tin­u­ous improve­ment and ear­ly response rather than reliance on one-time risk identification.

Relationship to the Early Identification System

PULSE is a stream­lined exten­sion of the Ear­ly Iden­ti­fi­ca­tion Sys­tem. It retains the con­cep­tu­al frame­work, fac­tor struc­ture, and pre­ven­tion ori­en­ta­tion of the EIS while sub­stan­tial­ly reduc­ing admin­is­tra­tion bur­den. The sys­tem is intend­ed to pro­vide a prac­ti­cal and scal­able method for imple­ment­ing uni­ver­sal screen­ing and ongo­ing mon­i­tor­ing in schools.

Positioning Within Nurturing Schools

PULSE aligns with the Nur­tur­ing Schools frame­work by treat­ing men­tal health as an out­come of every­day edu­ca­tion­al expe­ri­ences. The sys­tem not only iden­ti­fies stu­dent risk but also pro­vides action­able infor­ma­tion about the extent to which schools are fos­ter­ing con­di­tions asso­ci­at­ed with engage­ment, belong­ing, safe­ty, com­pe­tence, and healthy devel­op­ment. As such, PULSE func­tions as both a stu­dent well­be­ing assess­ment and a school func­tion­ing sur­veil­lance system.
