Type of Study: Randomized controlled trial
Number of Participants: 50 mother-child pairs

Population:

• Age — Mothers: Not specified; Children: 5–8 years
• Race/Ethnicity — Predominantly White
• Gender — Mothers: 50 Female; Children: 39 Male and 11 Female
• Status — Participants were mothers of children classified as learning disabled by educational guidelines.

Location/Institution: Texas

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to examine the efficacy of the Systematic Training for Effective Parenting (STEP) program on parent’s child-rearing attitudes for learning disabled children. Participants were randomly assigned to STEP treatment or to the control group. Measures utilized include the Parent Attitude Survey (PAS) and the Primary Self Concept Inventory (PSCI). Results indicate that parents in the treatment group improved their PAS scores, particularly in the areas of Acceptance and Trust. Children’s PSCI scores also showed improvements in the areas of Personal Self and Social Self. Limitations include small sample size and length of follow-up.

Length of controlled postintervention follow-up: 2 weeks.

Location/Institution: Brisbane, Australia

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to examine the efficacy of the Systematic Training for Effective Parenting (STEP) program on parental attitudes in an Australian sample. Participants were randomly assigned to receive the STEP program, or to a wait-list control group. Measures utilized include the Attitude Toward the Freedom of Children Scale II (ATFC-II) and the Parent Attitude Research Instrument Q4 (PARI Q4). Results indicate that mothers in the treatment group were found to be more democratic in their child-rearing attitudes after training. They also differed from control mothers on the Encouraging Verbalization and showed a decrease on the Strictness subscales of the PARI Q4. Limitations include small sample size, lack of diversity and self-selection into the study by mothers, and lack of follow-up.

Length of controlled postintervention follow-up: None.

Location/Institution: Lithuania

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to examine the short- and long-term efficacy of the Systematic Training for Effective Parenting (STEP) program on parents from Lithuania. Participants were assigned to either the STEP intervention group, an optional wait-list comparison group, or a non-treatment comparison group. Measures utilized include the Lithuanian STEP Parent Survey Form, the Parenting Styles and Dimensions Questionnaire–Short Form (PSDQ-Short Form), and the Adlerian Parental Assessment of Child’s Behavior Scale (APACBS). Results indicate that parents of both genders demonstrated an increase in knowledge on parenting related to child’s misbehavior, encouragement, discipline, logical consequences, and so forth. Mothers decreased the use of authoritarian and permissive parenting styles and perceived the targeted child’s behavior as less emotionally charging with a decrease in peer-related problematic behavior. Limitations include lack of randomization, lack of generalizability due to gender, and length of follow-up.

Length of controlled postintervention follow-up: 3–4 months.

Type of Study: Randomized controlled trial
Number of Participants: 21

Population:

• Age — Children: 3-8 years; Mothers: 20-45 years
• Race/Ethnicity — Children: Not specified; Mothers: 100% Latina
• Gender — Children: 12 Male and 8 Female; Mothers: 100% Female
• Status — Participants were low-income, immigrant Latina mothers reporting high levels of parental stress and child internalizing problems.

Location/Institution: Southeast region of the United States

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to examine the comparative effects of two empirically supported, manualized parenting programs, Child–Parent Relationship Therapy (CPRT) and Systematic Training for Effective Parenting (STEP). Participants were randomly assigned to either CPRT or STEP. Measures utilized include the Child Behavior Checklist (CBCL) and the Parenting Stress Index (PSI). Results for parental stress indicate no statistically or practically significant between-group differences. Within-group treatment effects reveal larger effects for the CPRT group for internalizing behavior problems and parental stress. Clinical significance of the findings indicate greater improvement for children and mothers in the CPRT group. Limitations include attrition rates differed greatly between CPRT and STEP, small sample size, lack of a non-treatment control group, and lack of follow-up.

Length of controlled postintervention follow-up: None.

Population:

• Age — Children: Less than 3 years; Mothers: Not specified
• Race/Ethnicity — Children: Not specified; Mothers: GABI: 47% Hispanic, 28% Black, 23% Biracial, and 2% White; STEP: 40% Hispanic, 37% Black, 17% Biracial, and 5% White
• Gender — Children: Not specified; Mothers: 100% Female
• Status — Participants were mothers at risk of maltreating their children.

Location/Institution: The Bronx, New York

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to report on a trial involving children less than 3 years old and their mothers who were regarded at risk of maltreating their children by referral agencies. Participants were randomly assigned to either Systematic Training for Effective Parenting (STEP) or the Group Attachment-Based Intervention (GABI). Measures utilized include the Coding Interactive Behavior (CIB) system, and the Adverse Childhood Experiences (ACEs). Results indicate that in comparison to STEP, GABI was linked to significant improvements in maternal supportive presence and dyadic reciprocity, and significant declines in maternal hostility and dyadic constriction (proxies for risk of child maltreatment). These medium-to large-sized effects remained significant even after controlling for mothers’ prior ACEs in analysis of covariance procedures. In addition, two small interaction effects of ACEs by treatment type were found. Limitations include different length (and characteristics) of treatment in the two arms, lack of follow-up, and high attrition rate.

Length of controlled postintervention follow-up: None.
