Insights
New research introduces the HELP-T Scale to measure post-separation abuse (PSA) tactics in healthcare, legal, and economic domains. This validated instrument aids professionals in understanding and addressing risks to child health.
Area of Science:
- Psychology
- Public Health
- Sociology
Background:
- Intimate partner violence (IPV) can persist after separation, termed post-separation abuse (PSA).
- Validated instruments are crucial for measuring PSA and mitigating risks to child health.
- Existing measures may not adequately capture the multifaceted nature of PSA.
Purpose of the Study:
- To develop and validate a new scale, the Healthcare, Economic, and Legal Post-Separation Abuse and Coercive Tactics (HELP-T) Scale.
- To assess the reliability and validity of the HELP-T Scale in a sample of maternal survivors experiencing PSA.
- To provide professionals with a tool to measure and understand PSA tactics.
Main Methods:
- Item generation through qualitative interviews with maternal survivors (N=33) and expert review.
- Psychometric testing including exploratory factor analysis for construct validity and Cronbach's alpha for reliability on a sample of 497 maternal survivors.
- Iterative principal factor analysis to identify subscales.
Main Results:
- The HELP-T Scale comprises 22 items across three subscales: Healthcare PSA, Legal PSA, and Economic PSA.
- The scale demonstrated strong reliability, with Cronbach's alphas ranging from 0.82 to 0.89 for the subscales.
- Preliminary psychometric properties indicate the scale effectively measures PSA tactics.
Conclusions:
- The HELP-T Scale is a reliable and valid instrument for measuring post-separation abuse.
- The findings provide valuable insights for health and legal professionals to identify and address PSA.
- This tool can contribute to better understanding and mitigating the impact of PSA on child health.
Abstract:
Validated instruments that measure intimate partner violence (IPV) following separation from an abusive co-parent ("post-separation abuse" (PSA)), are needed to understand and mitigate risks to child health. Items for the Healthcare, Economic, and Legal Post-Separation Abuse and Coercive Tactics (HELP-T) Scale were generated based on qualitative interviews with maternal survivors (N = 33) and expert review. Reliability, construct validity, and concurrent validity were tested in a sample (N = 497) of maternal survivors experiencing PSA in the US. Exploratory factor analysis assessed construct validity, and Cronbach's alpha assessed subscale reliability. Iterative principal factor analysis revealed 3 subscales for 22 items that were labeled (1) Healthcare PSA, (2) Legal PSA, and (3) Economic PSA, and demonstrated strong reliability with Cronbach's alphas from 0.82 to 0.89. The three subscales exhibit strong preliminary psychometric properties and provide insights to help health and legal professionals measure and establish PSA tactics.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
