Assessing stimulus preference using response force in a conjugate preparation: A replication and extension.

The current study examined 98 participants' preferences for five pictorial stimuli. The researchers used a verbal multiple-stimulus-without-replacement (VMSWO) preference assessment with each participant to identify high-preference and low-preference pictorial stimuli. Next, participants viewed each pictorial stimulus in a randomized order on a computer while using a hand dynamometer that measured the amount of force they exerted to increase or maintain the visual clarity of each image. The results indicate that over 75% of participants' force response ranks corresponded with participants' VMSWO high-preference stimuli, VMSWO low-preference stimuli, or both. The results of the current study provide further evidence for the use of conjugate schedules in the assessment of stimulus preference with potential for use as a reinforcer assessment. Implications along with directions for future research and limitations of the findings are discussed.

Comparing stimulus preference and response force in a conjugate preparation: A replication with auditory stimulation.

This study examined a conjugate approach for evaluating auditory stimulus preference for 81 participants using force as a continuous response dimension. First, the researchers used a verbal preference assessment to evaluate each participant's preference for listening to five genres of music. This process identified high-preference and low-preference music for each participant. Thereafter, the researchers exposed each participant to the five music genres in a randomized order while using a hand dynamometer to measure their response force to increase the auditory clarity of the music. The results indicate (a) 63% of the participants' high-preference music genres corresponded to the genre for which they exerted the highest mean force and (b) most participants' low-preference music genres corresponded to the genre for which they exerted the lowest mean force. These findings are consistent with those from Davis et al. (2021) and further support using conjugate preparations for measuring the relative value of some stimulus events.

Multiple schedules of conjugate reinforcement and extinction: A translational model for assessing automatically reinforced behavior.

This study evaluated the extent to which a conjugate reinforcement schedule (CONJ) involving a contingency between pedaling a stationary bike and viewing a preferred movie could serve as a translational preparation for the analysis of automatically reinforced behavior. In part, researchers examined whether providing participants with either an accurate or an inaccurate rule about the extinction (EXT) component of a multiple schedule (MULT) contributed to the development of control by the MULT (CONJ EXT) schedule. Results show schedule control emerged for four of five participants who received the accurate rule and none of the five participants who received the inaccurate rule. In addition, participants who received accurate rules typically increased pedaling during CONJ components that followed two consecutive EXT components, suggesting that they experienced deprivation for audio and visual stimulation generated by pedaling. These preliminary findings suggest that researchers could use this translational preparation to identify matched interventions for some automatically reinforced behavior.

Transition States in Single Case Experimental Designs.

The continuation of a baseline pattern of responding into a treatment phase, sometimes referred to as a "transition state," can obscure interpretation of data depicted in single-case experimental designs (SCEDs). For example, when using visual analysis, transition states may lead to the conclusion that the treatment is ineffective. Likewise, the inclusion of overlapping data points in some statistical analyses may lead to conclusions that the treatment had a small effect size and give rise to publication bias. This study reviewed 20 volumes in a journal that publishes primarily SCEDs studies. We defined a transition state as a situation wherein at least the first three consecutive data points of a treatment phase or condition are within the range of the baseline phase or condition. Results indicate that transitions states (a) were present for 7.4% of graphs that met inclusion criteria and (b) occurred for a mean of 4.9 data points before leading to behavior change. We discuss some implications and directions for future research on transition states.

An Interdisciplinary Approach to Treating Severe Behavior in a Juvenile Justice Facility: Teaching Behavioral Self-Management via Telehealth.

Adolescents living in residential juvenile justice facilities often receive mental health services during their stay to address committed offenses, yet some display challenging behavior during moments of conflict within the facility. These challenging behaviors could result in risk of harm to self or others, or the individual may experience punishment from facility staff. The purpose of this study was to explore the effects of an additive voluntary focused intervention for individuals who continued to display challenging behavior despite participation in "treatment as usual" in a juvenile justice facility. We implemented a self-management intervention, supported through interprofessional collaboration, via telehealth with four male adolescents. Using Behavior Skills Training, we taught participants to self-monitor precursors for challenging behavior and identify an alternative behavior to engage in to prevent overt challenging behavior events. Alternative behaviors were responses incompatible with the challenging behavior, or served as a rule to prompt self-management of further behavior. Results show all four participants increased their selection of alternative behaviors when presented with an evocative situation and a precursor for a severe behavior event during simulations. In addition, three participants stated they would use alternative behaviors across precursors not presented during teaching; however, two participants required booster sessions to maintain appropriate responding during simulations. Outside of simulated sessions, facility staff reported modest decreases in participants' challenging behavior during and after the intervention.

Eight Months of Telehealth for a State-Funded Project in Foster Care and Related Services: Progress Made and Lessons Learned.

In response to the COVID-19 pandemic, many behavior analysts and other health professionals modified their services for delivery via telehealth modalities. The transition to telehealth is especially important for providers working with foster youth who exhibit challenging behavior because these youth often move to another placement due to such behaviors. The primary objective of this article was to evaluate the extent to which service indicators for a state-funded team working with foster youth changed after the service delivery model changed from in-person to telehealth services. In particular, we evaluated changes in monthly count of client contacts, appointments, intakes, closed cases, and medication reviews. The secondary objective was to outline potential benefits and environmental barriers encountered by the team and to integrate our findings with the literature on behavior-analytic services provided via telehealth. Overall, results show that we maintained service quality with a broad range of behavioral interventions and increased overall client appointments. Given these outcomes, our team may continue to provide behavioral services via telehealth after the COVID-19 pandemic.

Improving Juvenile Justice Settings by Decreasing Coercion: One Lab's Perspectives from Behind the Fence.

In this article, we outline an emerging role for applied behavior analysis in juvenile justice by summarizing recent publications from our lab and discussing our procedures through the lens of coercion proposed by Goltz (2020). In particular, we focus on individual and group interventions that target a range of behaviors emitted by adolescents in a residential treatment facility. In general, individual interventions involve teaching adolescents to (1) respond appropriately to staff, (2) tolerate nonpreferred environmental conditions, and (3) control problematic sexual arousal. Likewise, group interventions involve low-effort manipulations that decrease disruptive behavior and increase appropriate behavior in settings with numerous adolescents. Thereafter, we describe behavioral interventions for staff working in juvenile justice. These staff-focused interventions aim to increase staff-initiated, positive interactions with students in order to change subsequent student behavior. In addition, we review our recent endeavors to assess and conceptualize other service providers' behavioral products (i.e., prescription practices) in a juvenile facility. Lastly, we discuss future directions of behavior-analytic intervention with juvenile-justice involved adolescents.

Increasing Praise Delivery Within Dorms of a Juvenile Justice Facility.

Researchers have shown that adolescents in residential treatment facilities benefit from behavior-analytic intervention. However, it remains unclear whether practitioners can apply behavioral interventions to increase staff members' appropriate interactions with residents within a juvenile justice facility. In Study 1, researchers compared direct measures of staff behavior in three target dorms (D1, D2, and D3) containing high levels of resident disruptive behavior to a dorm (D4) with consistently low levels of resident disruptive behavior. Results indicated that staff members in the target dorms engaged in significantly higher rates of reprimands and negative statements than in D4. In Study 2, researchers used didactic and video instruction to train staff members in D1, D2, and D3 to increase contingent and noncontingent praise delivery. Results indicated praise delivery by staff members increased slightly in each target dorm. In Study 3, researchers first evaluated the extent to which measures of staff members' and residents' behaviors improved following training within each dorm. Subsequently, researchers compared the post-training behavioral measures from D1, D2 and D3 to D4 to determine the extent to which staff behavior in the training dorms was distinguishable from D4. Results of Study 3 indicated that one or more staff behaviors improved in each training dorm. Nevertheless, residents' disruptive behavior was unchanged in each target dorm. In addition, staff members' behavior in each target dorm continued to be distinguishable from staff members' behavior in D4 on most behavioral measures.

A Pilot Study Exploring Social Validity Ratings of Social Profiles for College Students.

Nuhu and Rapp identified three profiles undergraduates displayed during social interactions. We evaluated the social validity of these three profiles in two studies. In Study 1 we presented video exemplars of speakers representing each profile to undergraduate participants and asked them to rate the speaker in respect to various statements. Results showed that one profile was rated significantly different than the other two profiles on all but one statement. In Study 2 we further evaluated the role of eye contact in the profile that participants rated differently in Study 1. Results from Study 2 showed that a speaker engaging in low eye contact was rated lower than a speaker engaging in either a validated or high level of eye contact. Likewise, participants with self-reported high social competency provided more negative ratings of a speaker who displayed low eye contact than participants with self-reported Moderate and Low social competency.

Comparing stimulus preference and response force in a conjugate preparation.

Researchers used a conjugate preparation to evaluate how response force changed based on participants' preferences for visual stimuli. First, researchers used a verbal preference assessment to evaluate each participant's preference for viewing for five object categories of visual stimuli; this process identified high preference (HP) stimuli and low preference stimuli for most participants. Thereafter, researchers exposed each participant to the five stimulus categories in a randomized order while using a force dynamometer to measure their response force to increase visual clarity of each stimulus. Results indicate the majority of participants' HP stimuli corresponded to the stimulus category for which they exerted the highest mean force. These preliminary findings suggest conjugate preparations involving response force may provide another option for measuring the relative value of some stimulus events.

Fluency and the Maintenance of Skills Related to Sex Laws for Individuals Adjudicated for Illegal Sexual Behavior.

Previous research has evaluated the effects of various commonly used mastery criteria on skill maintenance by directly manipulating the accuracy requirement, as well as the sessions across which these accuracy levels must be demonstrated. The current study extends this literature by including a rate dimension within the mastery criterion with a unique population. We implemented a fluency-oriented treatment package to increase intraverbal skills related to state sex laws using a multiple-baseline design across 3 target sets for 2 individuals adjudicated for illegal sexual behavior. Within this intervention package, we included 2 distinct components of a single mastery criterion: (a) accuracy (i.e., 100% accuracy across 3 consecutive sessions) and (b) speed. We evaluated how each of these measurable dimensions of behavior maintained across time. Results indicate this mastery criterion produced over 80% accuracy during maintenance probes for 10 weeks across all sets for both students. However, this mastery criterion produced idiosyncratic maintenance of rates across students and sets. These results suggest that each of these dimensions of behavior does not necessarily covary and should be conceptualized as distinct clinical targets by applied behavior clinicians.

Behavioral Skills Training to Increase Appropriate Reactions of Adolescent Males in Residential Treatment.

Adolescents in secured residential facilities may engage in excess behavior immediately following verbal directives or corrective statements from staff. Excess behavior may include verbal aggression, indices of disrespect (e.g., eye rolling, grunting, and obscene gestures), or even physical aggression. These excess behaviors may evoke further directives or corrective statements from staff that, in turn, escalate the adolescent's excess behavior and can produce undesirable effects for both the adolescent (e.g., loss of privileges) and staff members (e.g., increased burn out). Teaching detained adolescents to respond appropriately to staff directives and corrective statements may produce large collateral changes in the way staff interact with adolescents in detention facilities. These changes could be conceptualized as a behavioral cusp. We used behavioral skills training to teach 11 adolescent males to respond appropriately to staff directives. All 11 students showed low percentages of trials with appropriate reactions in baseline and high percentages of trials with appropriate reactions during treatment and generalization sessions. Further, two students showed maintenance of the skill 1 month and 5 months following treatment.

Tolerance Training with Adolescents in a Residential Juvenile Facility.

For individuals receiving treatment in residential juvenile facilities, the inability to tolerate typical but unpleasant stimulus events may manifest in aggressive behavior toward staff or other residents. Such behaviors can lead to loss of privileges, interfere with other treatments, and contribute to negative staff-student relationships. As a procedure, tolerance training (TT) involves systematically increasing the duration of exposure to an undesired stimulus event or situation. The current study evaluated the effects of a procedure to increase tolerance of aversive situations for four adolescents who were receiving treatment for sexual offenses in a residential detention facility. Results from single-subject experimental designs indicate that TT increased all four adolescents' ability to tolerate a non-preferred stimulus event. We briefly discuss the clinical implications of the use of behavior-analytic procedures to improve skill sets for adolescents in residential treatment facilities.

Effects of Obtrusive Observation and Rules on Classroom Behavior of Adolescents in a Juvenile Residential Treatment Setting.

Several studies have used interdependent group contingencies to decrease disruptive behavior and increase appropriate behavior for groups of adolescents. In addition, one study demonstrated that rules plus feedback about rule violations, without additional group contingencies, decreased problem behavior and increased appropriate behavior for adolescents in three classrooms within a residential juvenile facility. Given the rapid behavior change observed in the aforementioned study, it is possible behavior changes were produced by reactivity to obtrusive observation from program implementers. To address this question, we used two A-B designs in conjunction with the conservative dual-criterion (CDC) method to evaluate the extent to which obtrusive observation alone and rules, without systematic consequences, decreased problem behaviors in two classrooms within a residential juvenile facility. Results from visual and CDC analyses indicate that (a) obtrusive observation did not affect problem behavior in either classroom and (b) rules decreased problem behavior in both classrooms and increased appropriate behavior in one classroom. In addition, a measure of social validity indicated that the procedures and outcomes were acceptable to the classroom teacher.

Using Arousal Suppression Exercises to Decrease Inappropriate Sexual Arousal in Detained Adolescent Males: Three Clinical Demonstrations.

Reyes, Vollmer, and Hall (2011) found that 2 arousal suppression strategies, 1 of which involved counting backward from 100 to 0, decreased sexual arousal for 2 male sex offenders with intellectual disabilities. In the current clinical study, we taught 3 adolescent males who had been adjudicated for illegal sexual behavior to self-report arousal when they were presented with sexually arousing visual stimuli. Based on the procedures in the Reyes et al. (2011) study, we taught participants to count backward from 100 to 0 when they verbally reported a criterion level of sexual arousal in the presence of visual media. Subsequently, we gradually faded therapists' instructions for 2 participants until they independently used the arousal suppression exercise. Results showed that each participant's self-reported sexual arousal decreased upon implementation of treatment relative to baseline. Decreased sexual arousal continued even under conditions of faded therapist instructions for 2 participants. The relative merits of using self-report measures are discussed.

Enhancing the Lives of Foster Youth with Behavioral Interventions.

As members of state-funded team to monitor psychotropic medication use and examine cost-effective methods for behavioral treatment in foster care, the authors review behavioral studies on interventions for foster youth who engage in challenging behavior. Four behavioral technologies-preference assessments, teaching procedures, functional behavioral assessment and intervention, and parent training-are discussed. Four case studies and behavioral data for foster youth treated using these technologies are provided. Finally, pediatric providers are encouraged to recommend a practitioner with specialized training in behavior analysis to foster parents if a child displays disruptive behavior.

Does Awareness of either Psychotropic Medication or Behavioral Interventions Bias College Students' Ratings of a Child's Behavior?

Caregiver awareness that a child receives either psychotropic medication or behavioral intervention could bias that caregiver's perception of the child's behavior and give rise to incorrect conclusions about intervention effectiveness. To evaluate bias for the effects of either medication or behavioral intervention, we randomly assigned 114 participants to one of the four groups: Medication information (Med info), Behavioral information (Beh info), No change (control group), and Reverse video (Rev Vid; also no change, but participants watched videos in the reverse order). Participants watched two 5-min video clips of a child engaging in low to moderate levels of problem behavior. After watching the first video, participants rated the child's problem behavior. Before viewing the second video, participants were informed that (a) the child received medication (Med info group), (b) the child received behavioral intervention (Beh info group), or (c) no treatment changes were made (No change groups). Results show that providing treatment information did not bias participants' ratings of the child's behavior. Instead, results indicate participants in the control groups correctly tracked actual changes in the child's behavior.

Behavioral skills training to increase interview skills of adolescent males in a juvenile residential treatment facility.

Some studies suggest that acquiring employment following release from prison may reduce recidivism; however, few studies have evaluated procedures for teaching job-related skills to adolescents in residential detention facilities. Stocco et al. (2017) used behavioral skills training (BST) to improve interview skills of college students. The current study used a nonconcurrent multiple baseline design across participants to evaluate the extent to which BST improved interview skills for 7 adolescents who had been adjudicated for sexual offenses. Results show that BST increased appropriate responses to interview questions for 4 students and BST plus modifications (i.e., stimulus and response prompts) increased correct responding to questions for the other 3. In addition, BST increased appropriate questions, correct posture, and smiling, and decreased fidgeting for all 7 students. We briefly discuss the social implications of teaching interview skills to adjudicated adolescents, as well as the limitations of the findings.

To What Extent Do Practitioners Need to Treat Stereotypy During Academic Tasks?

Researchers frequently argue that a child's engagement in stereotypy may compete with his ability to acquire academic skills, engage in appropriate social interactions, or both; however, few studies have directly tested these suppositions. We used a five-phase assessment to evaluate the extent to which behavioral interventions with a progressively greater number of components were necessary to decrease stereotypy and increase correct responding during academic instructions for five children diagnosed with autism spectrum disorders. For one participant, stereotypy decreased when instructors provided standard instruction without specific intervention for stereotypy. For two participants, stereotypy decreased when instructors provided standard instruction plus antecedent intervention for stereotypy with continuous music. For another participant, stereotypy decreased when instructors provided enhanced consequences for correct responding during standard instruction without either antecedent or consequent intervention for stereotypy. For the final participant, stereotypy decreased and correct responding increased when instructors provided standard instruction and consequent intervention for stereotypy.

Using a Multiple-Schedule Procedure to Signal the Availability of Attention: Three Demonstrations.

Adjudicated adolescents detained in residential facilities for illegal sexual behavior, as well as adolescents living at home, may engage in problem behaviors such as excessive vocalizations. In residential detention facilities, these excessive vocalizations may result in disciplinary action and loss of privileges. Moreover, excessive vocalizations may also reduce the amount of positive social interactions that staff members and caregivers have with the adolescents. The current study evaluated a multiple-schedule procedure for reducing excessive vocalizations displayed by three adolescents. The procedure involved (a) a red card to signal that attention was not available and (b) either a green card or no card to signal that attention was available. Results show that the participants learned to abstain from vocalizing for up to 30 min when a caregiver presented the red card. In addition, the treatment effects persisted during generalization assessment sessions.
