Effects of Schoolhouse-Broad Positive Behavioral Interventions and Supports on Child Behavior Problems

Abstract

OBJECTIVE:

School-Wide Positive Behavioral Interventions and Supports (SWPBIS) is a universal prevention strategy currently implemented in >16 000 schools across the United States. SWPBIS intends to reduce students' behavior issues by altering staff behaviors and developing systems and supports to meet children's behavioral needs. The current study reports intervention effects on child behaviors and aligning from an effectiveness trial of SWPBIS.

METHODS:

The sample of 12 344 uncomplicated school children was 52.9% male, 45.1% African American, and 46.one% Caucasian. Approximately 49% received free or reduced-priced meals, and 12.9% received special education services at baseline. The trial used a group randomized controlled effectiveness design implemented in 37 unproblematic schools. Multilevel analyses were conducted on teachers' ratings of children's behavior problems, concentration issues, social-emotional functioning, prosocial behavior, role discipline referrals, and suspensions at five fourth dimension points over the grade of 4 schoolhouse years.

RESULTS:

The multilevel results indicated significant effects of SWPBIS on children's beliefs problems, concentration problems, social-emotional functioning, and prosocial behavior. Children in SWPBIS schools also were 33% less likely to receive an office discipline referral than those in the comparing schools. The effects tended to be strongest among children who were commencement exposed to SWPBIS in kindergarten.

CONCLUSIONS:

These findings provide support for the hypothesized reduction in behavior issues and improvements in prosocial behavior and constructive emotion regulation afterward grooming in SWPBIS. The SWPBIS framework appears to be a promising approach for reducing problems and promoting adjustment among unproblematic school children.

What'south Known on This Subject:

School-Wide Positive Behavioral Interventions and Supports (SWPBIS) is a widely used universal prevention strategy currently implemented in >16 000 schools beyond the United States. Previous research has shown positive furnishings on schoolhouse climate and school-level discipline problems.

What This Study Adds:

This study reports multilevel results on data from a four-yr randomized controlled effectiveness trial of SWPBIS in 37 simple schools. Results indicate significant impacts on children's aggressive behavior problems, concentration problems, office discipline referrals, emotion regulation, and prosocial behavior.

Deport and confusing beliefs bug pose a significant concern for children'south development. An onset of disruptive and aggressive behavior problems in elementary school is associated with an increased risk for academic problems, placement in special educational activity programs, school dropout, substance abuse bug, and antisocial beliefs.^{ane , 2} In that location is growing interest in schoolhouse-wide prevention models, such as Schoolhouse-Wide Positive Behavioral Interventions and Supports (SWPBIS),^{three , 4} as an approach for preventing an early-onset of behavior problems and promoting positive aligning.

SWPBIS is a noncurricular universal prevention strategy that aims to modify the school'southward organizational context to implement enhanced procedures and systems to guide information-based decisions related to educatee behavior problems and academics. It applies behavioral, social learning, and organizational principles to an entire student body consistently beyond all school contexts.⁵ Schools establish a gear up of positively stated, school-wide expectations for educatee behavior, which are taught to all students and staff. It aims to prevent confusing behavior and raise organizational climate by implementing a 3-tiered prevention framework^half-dozen in which 2 levels of selective and indicated programs are implemented to complement the universal school-broad components (for a review, run into Sugai and Horner, Taylor-Greene and Kartub, and Horner et al^{iii , 4 , 7 , viii}). However, most of the >sixteen 000 schools currently implementing SWPBIS have focused on the universal components (come across pbis.org).

Ii randomized controlled trials (RCTs) were recently conducted of SWPBIS in elementary schools and indicated positive outcomes for students and staff. Specifically, a 1-twelvemonth waitlist RCT indicated significant improvements in school climate and accomplishment.⁹ Previous studies reporting data from the current sample of 37 elementary schools enrolled in a four-yr RCT indicated significant improvements in the schools' organizational health, schoolhouse-level subject area data, and the implementation of classroom-based supports.^{10 – 12} To date, there has been no research using longitudinal RCT designs that has examined the effect on instructor ratings of behavior issues and social-emotional adjustment.

We used data from the 4-twelvemonth RCT to examine the hypothesis that children in schools implementing SWPBIS would accept better teacher-rated emotion regulation and prosocial behaviors and fewer concentration problems and disruptive behaviors. We also hypothesized that children in SWPBIS schools would be less likely to be referred to the chief's part or suspended. Given the group RCT design (ie, students nested within schools), we used a multilevel modeling approach^xiii and adjusted for select covariates at the school (eg, enrollment) and kid levels (eg, gender).¹⁴ These findings will enhance our understanding of the effects achieved through the usually used SWPBIS approach by determining its impact on a range of outcomes.

Method

Design

Data came from a grouping randomized controlled effectiveness trial^{xiii , 15} of the universal SWPBIS model that aimed to determine the impact of SWPBIS on discipline bug and the school surroundings. Only public simple schools were eligible for inclusion, and all schools approached about participation agreed to enroll. An open-accomplice design was used, such that new students could enroll at each information drove; nevertheless, resources were not available to follow students who left the participating schools. Schools were matched on select baseline demographics (eg, school enrollment), of which 21 schools were randomized to the intervention condition and 16 to the comparison status. The comparing schools refrained from implementing SWPBIS for 4 years.

Training

The 21 schools assigned to receive SWPBIS preparation each formed SWPBIS teams, comprising 5 to 6 members (eg, teachers, administrators), who attended an initial 2-day summer training co-led past one of the developers of SWPBIS. To maintain consistently high levels of fidelity, the SWPBIS teams attended almanac 2-day booster training events. Consistent with the effectiveness trial blueprint,¹⁵ all initial preparation and booster preparation events were coordinated and led by the PBIS Maryland Country Leadership Squad and were also attended by other SWPBIS teams from beyond the state.^sixteen All SWPBIS schools received at least monthly on-site support and technical assistance from a trained beliefs support jitney (eg, school psychologist) for the duration of the trial; these staff were trained by the state and supervised by the commune. Professional evolution and technical assistance were provided to the behavior support coaches through state-coordinated training events conducted iv times each year (meet Barrett et al¹⁷ for additional information).

Fidelity

Annual assessments of SWPBIS implementation were conducted in all 37 schools by trained assessors who were unaware of the schools' implementation condition using the validated School-wide Evaluation Tool (Fix)¹⁸ and staff self-reports^{xi , 12}; both indicated that all SWPBIS schools reached and maintained high-fidelity implementation (eg, eighty% on the School-wide Evaluation Tool)^xviii by the end of the trial, and no schools in the comparison status consistently reached high fidelity; 66% of the SWPBIS schools met the 80% loftier-fidelity threshold¹⁸ inside the kickoff year of the trial (run into means in Fig 1 and Bradshaw et al^{11 , 12 , xix} for additional information on the methods and fidelity in the intervention and control weather condition).

Mean School-wide Evaluation Tool (Prepare) allegiance scores at SWPBIS and comparison schools at baseline and years 1 through iv. Analysis of the Gear up data suggested a significant effect (ie, intervention condition × time interaction) for the overall Set up score; Wilks' Λ = .38, F(iv,32) = thirteen.36, P = .001, η2 = .63, d = 3.22.

Sample

The sample included 37 elementary schools, the size of which was determined through a ability assay. Five data points (fall and jump twelvemonth one, spring years 2-4) were collected over the 4 school years (2002–2007) on 12 334 children who were in kindergarten, beginning, and second grade when the study started.

Measures

The Teacher Observation of Classroom Accommodation—Checklist (TOCA-C)²⁰ was completed for each kid past their primary classroom teacher. The TOCA-C is a checklist version of the TOCA (TOCA-R),²¹ which has been used in several previous RCTs of school-based prevention programs.^{22 – 24} The TOCA-C measures each child'southward level of "aggressive and confusing behaviors" (fights; 9 items, α = .92), "concentration problems" (pays attention; 7 items, α = .96), "prosocial behaviors" (shows empathy; 5 items, α = .92), and "emotion regulation" (stops and calms downwards when angry or upset; 4-items, α = .89). Teachers responded to each question using a vi-point Likert scale (1 = never to six = near ever), which were averaged to create the 4 subscales, such that higher scores on disruptive behaviors and concentration problems indicated greater problems, whereas college scores on the prosocial behaviors and emotion regulation scales reflected better adjustment. These scales exhibit potent internal consistency, take a consequent cistron structure over time,²⁰ relate to external criteria,²⁵ and are sensitive to relatively pocket-size intervention effects.²⁶ The TOCA-C also included questions regarding each child'due south receipt of an office disciplinary referral (ODR) and an out-of-school suspension during that school year using a yes/no dichotomous format. Instructor reports of these events have been shown to be a valid indicator of the kid's discipline problems.²⁷ These items were collapsed over the 5 time points to create an aggregated dichotomous indicator for ODRs and suspensions (one = ever, 0 = never received) over the grade of the trial.

Procedure

Survey packets were mailed to the school and distributed to the teachers by an administrator or secretary. The packets independent a checklist in reference to each child in their classroom, and each survey had a unique identifier for each child, thereby allowing child-specific data to be tracked over the 4 years. Teachers completed a survey for each child in the course 5 times over the grade of four years (ie, fall baseline, spring of 4 years). The project was approved past the researchers' institutional review board; passive parental consent was used for child participants.

Analyses

Longitudinal 3-level hierarchical linear models were estimated past using hierarchal linear modeling (HLM6)²⁸ to examine the issue of SWPBIS on children's changes in behaviors (disruptive behaviors, prosocial behaviors, concentration problems, emotion regulation) over the grade of the intervention (Figs 3, ​ four, ​ five, and ​ 6). At level 1, the within-individual fourth dimension scores were entered into the model. At level 2, child characteristics (ie, special pedagogy status, race [blackness vs nonblack children], accomplice, free or reduced meals status, gender) were included. Given the group RCT pattern, intervention status (SWPBIS vs command) was modeled as a school-level characteristic (level 3). Additionally, multilevel logistic regression analyses were conducted in HLM to examine the effect of SWPBIS (modeled every bit a school-level variable) on receiving an ODR and a suspension.

On the basis of previous research with this data,^{11 , 12} the following school-level variables were included as covariates: student mobility, enrollment, student/instructor ratio, and kinesthesia turnover rate. We grand-mean centered all predictor variables at levels 2 and 3, except intervention status.²⁹ Model fit indices (Akaike information criterion [AIC] and Bayesian information criterion [BIC]) are reported in the tables and are interpreted such that smaller values indicate better fit.²⁸

Although the participation rate was consistently high, we examined the missing data patterns simply did not observe evidence that missingness was problematic.^{xxx , 31} For instance, baseline scores on concentration bug were unrelated to subsequent missingness on this measure (adjusted odds ratio [AOR] = 1.00, 95% confidence interval = 0.96–1.04). Baseline scores on confusing behavior were significantly associated with an increased odds of subsequent missingness (AOR = 1.05, 95% confidence interval = 1.03–ane.07), nonetheless this difference was minor and likely has limited clinical significance. Neither gender nor intervention status had a significant effect on subsequent missingness on teacher ratings of behavior problems. Therefore, our analyses assumed data were missing at random, which assumes that the reason for missingness is non related to the missing value itself or is deemed random afterward controlling for the variables that are observed.^{32 , 33} HLM adjusts parameter estimates for compunction using total-data maximum-likelihood estimation, a widely recognized and appropriate means of handling missing data³⁴ nether the supposition that information are missing at random.³⁵ Specifically, individuals can have missing data across whatsoever of the time points and even so be included in the analyses; therefore, HLM is robust to missing data within repeated measures.^{35 , 36}

Results

The sample of 12 344 children was 52.9% male person, 45.i% African American, and 46.i% Caucasian (encounter Tabular array 1). Approximately 49% received free or reduced-price meals, and 12.9% received special instruction services. The multilevel analyses indicated a pregnant positive intervention outcome on confusing behaviors (γ = –0.02, t = –ii.23, P < .05, effect size (ES) = 0.12), such that children in SWPBIS schools had lower levels of aggressive and confusing behaviors compared with those in the control schools (see Table 2). A similar effect was observed on concentration issues (γ = –0.03, t = –two.08, P < .05, ES = 0.08; come across Table 3). We explored for possible cross-level interaction furnishings between SWPBIS and class accomplice, gender, and special pedagogy status; however, none were significant.

The multilevel analyses too indicated a significant intervention event on prosocial behavior (γ = 0.03, t = two.11, P < .05, ES = –0.17), such that children in the intervention had college levels of positive behaviors compared with those in the control. A similar effect was observed on emotion regulation (γ = 0.03, t = 2.30, P < .05, ES = –0.11), such that children in the intervention schools had amend emotion regulation than those in the control. Again we examined for possible interaction furnishings of intervention status and grade cohort, gender, and special education. The results indicated that children who were in kindergarten when the trial began fared meliorate in SWPBIS schools than in comparison schools on both prosocial beliefs (γ = 0.08, t = ii.77, P < .01) and emotion regulation (γ = 0.05, t = 2.38, P < .05). No other interactions were meaning (come across lesser of Tables 4 and ​ five for interaction terms only). We explored the fit of quadratic and cubic growth in the HLM analyses for these continuous outcomes; however, neither resulted in a significant improvement in model fit.

The final ready of multilevel analyses indicated that children in SWPBIS schools were 33% less probable to receive an ODR than those in the comparison schools (AOR = 0.67, [0.57–0.79], P < .001). We also found a meaning interaction between gender and intervention status (AOR = ane.27 [ane.04–1.56], P < .05) in which girls in SWPBIS schools were less probable to receive an ODR than girls in comparison schools, but at that place was no difference for boys. With regard to suspensions, at that place were no significant differences between SWPBIS and comparison schools and no significant interactions (see Table 6).

This study used information from a 4-yr randomized controlled effectiveness trial to examine the hypothesis that children in schools implementing SWPBIS would experience ameliorate adjustment and fewer trouble behaviors relative to their peers in comparing schools. As hypothesized, the multilevel, longitudinal analyses indicated that relative to the children in comparison schools, those in SWPBIS schools displayed lower levels of disruptive behavior problems and concentration problems, and better emotion regulation and more prosocial beliefs. We also observed pregnant intervention effects on children's odds of receiving an ODR. Still, no meaning effects were observed on suspensions. Nosotros explored for potential interactions with select demographic variables and more often than not constitute that the effects were strongest among those children who began the trial when they were in kindergarten. Interestingly, no other demographic characteristics explored were significant upshot modifiers.

It was not surprising that one of the strongest furnishings was on ODRs, given a core component of the SWPBIS model is the establishment of a organization to track, monitor, and employ ODR data.⁴ The heightened attention to this particular source of data within SWPBIS probable contributed to the reduction in the odds of ODRs observed among children in the trained schools. Although not specifically examined inside this study, it is theorized that the reduction in ODR use is mediated by reductions in children's beliefs problems. Future studies should explore the extent to which the reductions in teacher-rated behavior problems pb to the reductions in ODRs. Although the current study focused on the overall touch on receipt of ODRs, it is possible that the design of findings may vary by the reason for the ODR (eg, bullying, disrespect); even so, data regarding these outcomes are not bachelor for schools in both conditions. It is as well possible that the more proximal impacts observed in the trial translate into longer-term effects on the need for school-based services, such as special teaching, and bookish outcomes.

Previous studies have reported a school-level impact of SWPBIS on suspension rates^{9 , 12}; therefore, we hypothesized that at that place would exist a significant upshot on students' receipt of a suspension; however, such an effect did not attain significance. It is possible that the intervention effects would increase with longer implementation of the model. More targeted strategies, such every bit those used in the full 3-tiered SWPBIS model, may exist necessary to reduce suspensions. Furthermore, we only explored main effects of the universal SWPBIS model and select interactions related to demographics, which indicated that the furnishings tended to exist strongest for children who were in kindergarten when they were kickoff exposed to SWPBIS. This suggests that the earlier the exposure to SWPBIS, the greater the potential touch on of the model. From a developmental perspective, it is possible that younger children's behaviors are more malleable and responsive to adults' expectations and positive reinforcement for good behavior. Boosted work is needed to ameliorate understand the bear upon of SWPBIS when implemented in middle and loftier schools. Futurity studies also should examine whether the intervention furnishings are greatest for children with a particular baseline risk profile.³⁷ Although not a focus of the current written report, race and special education status were significantly associated with each result across all models. Given the literature on disproportionality in discipline,³⁸ futurity research will examine the furnishings on disproportionality in special education service apply and subject field issues.

The data were obtained through teacher reports over the course of the trial because archival information (eg, ODRs) or pretraining teacher-report information are not available for analysis. Although we recognize that a teacher study of need is not equivalent to an cess made by a clinician or a diagnostic cess, teachers are the most common source of children'due south mental wellness and special education referrals,³⁹ thus their assessments are of import in the context of school-based interventions and have been shown to predict mental health problems.^{2 , 20} Furthermore, the SWPBIS and control schools did not have common measurement systems for ODRs that would permit a functional comparison of these data elements; however, teacher reports of ODRs have been validated.²⁷ Future research should examine other effects of SWPBIS, such equally the impact on achievement and attendance.

The effect sizes were relatively small; however, small effect sizes are common in longitudinal universal prevention studies^{xv , forty}; nosotros conceptualize that the effects will be stronger for higher-risk students.²⁴ Also bear in mind that the RCT was an effectiveness trial in which all the training, implementation, and support activities were led by the country and local schoolhouse districts, non by the researchers. These training events also included schools not participating in the RCT, and thus nosotros conceptualize that the findings would generalize to other schools in the state who participated in these events (see Stuart et al⁴¹ for information on generalizability).

Conclusions

This is the first RCT to demonstrate impacts of SWPBIS on trajectories of children's behavior problems and adjustment over multiple school years. These findings propose that at that place are proximal effects of SWPBIS on a range of behavior bug, such every bit ODRs, concentration difficulties, and aggressive or confusing behavior, as well as improvements in prosocial behaviors and emotion regulation. The effects of SWPBIS on prosocial beliefs and emotional regulation are relatively unique in the literature. The finding that these effect sizes were as strong as or stronger than confusing behavior is likewise noteworthy. Demonstrating the impact of SWPBIS on a range of early on-onset behavior and social-emotional problems has of import public health significance, especially in light of the wide dissemination of SWPBIS.²⁹

These findings provide support for the hypothesized reduction in beliefs bug and improvements in adaptive skills through SWPBIS. Although these effects are promising, there are some children who are not responding adequately to the universal model,^iv and thus boosted piece of work is needed to identify these children so that their needs can be improve met within the school. The tiered prevention model besides provides an infrastructure for the delivery of more than intensive services and programs for children with greater needs.^{4 , 42} Furthermore, SWPBIS holds promise for improving the organizational context to back up higher-quality implementation of selective and indicated preventive interventions for nonresponders.^xi
