How does hostile resistance interfere with the benefits of cognitive-behavioral therapy for panic disorder? The role of therapist adherence and working alliance.

Objective Although clients' hostile behavior directed at therapists (hostile resistance) predicts worse outcomes in cognitive-behavioral therapy (CBT) for panic disorder, the process by which this happens remains unknown. This study examines two putative mechanisms: working alliance and therapist adherence. Method: Seventy-one adults with primary panic disorder received CBT in a larger trial. Hostile resistance and adherence in Sessions 2 and 10 were reliably coded using observer-rated measures; client- and therapist-rated questionnaires assessed working alliance. Outcome measures were attrition and symptomatic improvement, assessed at multiple timepoints with the Panic Disorder Severity Scale. Results: Hostile resistance was significantly related to both preexisting (r = -.36, p = .04) and subsequent declines (r = -.58, p < .0001) in the working alliance. Nevertheless, hierarchical linear modeling revealed that neither a declining alliance nor therapist adherence (whether treated as linear or curvilinear) was independently predictive of symptom change, nor did these factors mediate hostile resistance's association with worse symptomatic improvement. Exploratory logistic regressions similarly indicated that neither adherence nor alliance moderated whether hostilely resistant clients dropped out. Conclusion: This is the first study to establish a bidirectional association between hostile resistance and a declining working alliance. Findings also add to a mixed literature on the adherence-outcome relationship.

Psychometric properties of concussion knowledge and cognitive mediators of reporting measures.

Context: Concussion education and prevention programs require reliable and valid instruments to evaluate the theory, mechanisms, and outcome of these interventions Objective: To assess the psychometric properties of measures evaluating concussion education and prevention programsDesign: Descriptive epidemiological Setting: 10 NCAA-member universities Patients or Other Participants: 841 student-athletes in an RCT control group testing an ecological, peer-led concussion education program Main Outcome Measures: Instruments adapted for assessing concussion knowledge and Theory of Planned Behavior/Theory of Reasoned Action (TPB/TRA) cognitive mediators of reporting behavior (attitudes, subjective norms, perceived control, and intentions to report concussion). Participants completed measures at baseline, after one hour, and after one month Results: Internal consistency and test-retest reliability were moderate for both the concussion knowledge and cognitive mediator measures. TPB/TRA was supported subscale intercorrelation and item factor analysis in the cognitive mediator scale. Factor analysis of the concussion knowledge measure revealed subscales for physical/cognitive, psychological/affective, and non-symptoms. The intermediate TPB/TRA mediators of attitudes, norms, and perceived control predicted greater intention-to-report, which predicted increased likelihood of reporting concussion one month later.Conclusions: Measures of concussion knowledge and cognitive mediators of reporting adapted from the literature show adequate psychometric properties and support TPB/TRA application for concussion reporting behaviors.

Processes of therapeutic change: Results from the Cornell-Penn Study of Psychotherapies for Panic Disorder.

To examine process of changes in two distinct psychotherapies-cognitive-behavioral therapy (CBT) and Panic-Focused Psychodynamic Psychotherapy (PFPP). Two hypothesized processes of change-misinterpretation of bodily sensations and Panic Specific Reflective Function (PSRF)-were tested in the CBT and PFPP arms of the Cornell-Penn Study of Psychotherapies for Panic Disorder. The Brief Bodily Sensations Interpretation Questionnaire (BBSIQ) measures misinterpretation of bodily sensations-a focus of CBT interventions. PSRF, a target of PFPP, assesses the capacity to reflect on the underlying meaning of panic symptoms. A sample of 138 patients (37.7% men, 72.56% Whites, and 16.7% Latinx) with primary Diagnostic and Statistical Manual for Mental Disorders-Fourth Edition (DSM-IV) panic disorder were included in the present analyses. Mixed effects models tested the effects of early change in BBSIQ and PSRF (intake through Week 5) on subsequent change in the Panic Disorder Severity Scale (PDSS; Week 5 through termination). Early change on both PSRF and BBSIQ predicted subsequent change in panic severity across the two treatments. As predicted, PSRF changed more in PFPP than in CBT, but, contrary to expectation, BBSIQ showed comparable changes in both groups. Counterintuitively, CBT patients benefited more in terms of panic symptom improvement when their PSRF improved than did PFPP patients. This is the first demonstration of general processes of change (PSRF and BBSIQ) across psychotherapies for panic disorder, suggesting that to the extent patients change their beliefs about the meaning of panic, their panic symptoms improve in time-limited, panic-focused psychotherapies.

Differential effects of alliance and techniques on Panic-Specific Reflective Function and misinterpretation of bodily sensations in two treatments for panic.

ABSTRACTObjective: To examine whether working alliance quality and use of techniques predict improvement in Panic-Specific Reflection Function (PSRF), and misinterpretation of bodily sensations in treatments for panic disorder. Method: A sample of 161 patients received either CBT or PFPP (Panic-focused Psychodynamic therapy) within a larger RCT. Data were collected on patient-reported working alliance, misinterpretations, PSRF, observer-coded use of techniques, and interviewer-rated panic severity. Random-Intercept Cross-Lagged Panel Models assessed bi-directional associations, disentangling within- and between-patient effects, and accounting for prior change. Results: Higher alliance predicted subsequent within-patient improvement in PSRF in PFPP, but worsening in CBT. In both treatments, focus on interpersonal relationships predicted PRSF improvement (with stronger effects in CBT), while focus on thoughts and behaviors predicted worsening in PSRF. In CBT only, early focus on affect and moment-to-moment experience predicted reduced misinterpretation, while high focus on thoughts and cognitions predicted subsequent increase in misinterpretation. Conclusion: The quality of the alliance has differential effects on PSRF in distinct treatments. Interpersonal, rather than cognitive or behavioral focus, even when delivered differently within distinct treatments with high adherence, could facilitate improvement in PSRF. Additionally, early focus on affect and moment-to-moment experiences in CBT could reduce misinterpretations.

Postelection stress: Symptoms, relationships, and counseling service utilization in clients before and after the 2016 U.S. national election.

The 2016 U.S. national election brought increased anxiety, relationship conflict, and counseling utilization for many Americans, especially among women, millennials, racial and ethnic minority (REM) members, and economically disadvantaged persons. The present study examined psychological symptoms, interpersonal tension, and counseling service requests over 36 months of data (April 2015-March 2018) from 56 clients and 14 therapists engaged in a routine outcomes monitoring project at a training community counseling center. Clients resided in a Democratic-leaning area in a Republican-voting state, and 78% were women, 53% were under 30 years of age, 33% were an REM, and 92% earned below the median state income level. Symptoms did not show an association with the political climate, and interpersonal problems reduced during counseling. Although interpersonal conflict decreased prior to the election, it increased afterward, largely due to problems of dominance and control in relationships. Younger and REM individuals showed larger increases in interpersonal tension after the election than did older and non-REM persons. Alliances decreased over the entire data-collection period. Counseling intakes increased after the election, although potentially due to seasonal patterns. With attention to the effect of political events on individuals, the field of counseling psychology may be able to help clients and the larger society manage difficult interactions around real differences in political opinions and disparities.

The Multitheoretical List of Therapeutic Interventions - 30 items (MULTI-30).

Objective: To develop a brief version of the Multitheoretical List of Therapeutic Interventions (MULTI-60) in order to decrease completion time burden by approximately half, while maintaining content coverage. Study 1 aimed to select 30 items. Study 2 aimed to examine the reliability and internal consistency of the MULTI-30. Study 3 aimed to validate the MULTI-30 and ensure content coverage. Method: In Study 1, the sample included 186 therapist and 255 patient MULTI ratings, and 164 ratings of sessions coded by trained observers. Internal consistency (Chronbach's alpha and McDonald's omega) was calculated and confirmatory factor analysis was conducted. Psychotherapy experts rated content relevance. Study 2 included a sample of 644 patient and 522 therapist ratings, and 793 codings of psychotherapy sessions. In Study 3, the sample included 33 codings of sessions. A series of regression analyses was conducted to examine replication of previously published findings using the MULTI-30. Results: The MULTI-30 was found valid, reliable, and internally consistent across 2564 ratings examined across the three studies presented. Conclusion: The MULTI-30 a brief and reliable process measure. Future studies are required for further validation. Clinical or methodological significance of this article: The MULTI-30, developed and validated in this study, is a valid, reliable, and cost-effective brief measure which could be used to assess patients, therapists, and observers' perceptions of use of interventions from eight major therapeutic approaches. The MULTI-30 could be used to examine the role of use of specific interventions on process and outcome of different treatment modalities. It could also be used as a clinical tool in teaching, training, and supervision.

Client resistance predicts outcomes in cognitive-behavioral therapy for panic disorder.

Objective: Little is known about how therapy processes relate to outcome in cognitive-behavioral therapy (CBT) for panic disorder (PD). This study examined whether client resistance predicts CBT for PD outcomes beyond the effects of established pre-treatment predictors. A secondary aim was to assess the consistency of resistance over treatment. Method: Data were from 71 adults participating in up to 24 biweekly sessions of CBT in a randomized controlled trial. Panic severity was assessed before, during (at Weeks 1, 5, and 9), and at termination of treatment (Week 12) using the Panic Disorder Severity Scale. Trained coders reliably rated resistance in videos of Sessions 2 and 10 using the Client Resistance Code. Results: Resistance was found to be moderately consistent (r = .64). Although overall resistance was unrelated to outcomes, hierarchical linear modeling revealed that openly hostile resistance at Session 10 predicted significantly diminished symptom change (r = .28, CI95% = [.01, .51]), beyond the effects of pretreatment predictors. Hostile resistance at Session 2 predicted attrition (rrb = -.30, p = .001), even after established predictors were controlled. Conclusions: Although some forms of resistance may be benign, openly hostile resistance is an important therapy marker that warrants increased clinical and research attention.

Fluctuations in alliance and use of techniques over time: A bidirectional relation between use of "common factors" techniques and the development of the working alliance.

OBJECTIVE: The aim of this study was twofold: (a) Investigate whether therapists are consistent in their use of therapeutic techniques throughout supportive-expressive therapy (SET) and (b) Examine the bi-directional relation between therapists' use of therapeutic techniques and the working alliance over the course of SET. METHOD: Thirty-seven depressed patients were assigned to 16 weeks of SET as part of a larger randomized clinical trial (Barber, Barrett, Gallop, Rynn, & Rickels, ). Working Alliance Inventory-Short Form (WAI-SF) was collected at Weeks 2, 4, and 8. Use of therapeutic interventions was rated by independent observers using the Multitheoretical List of Therapeutic Interventions (MULTI). Intraclass correlation coefficients assessed therapists' consistency in use of techniques. A cross-lagged path analysis estimated the working alliance inventory- Multitheoretical List of Therapeutic Interventions bidirectional relation across time. RESULTS: Therapists were moderately consistent in their use of prescribed techniques (psychodynamic, process-experiential, and person-centred). However, they were inconsistent, or more flexible, in their use of "common factors" techniques (e.g., empathy, active listening, hope, and encouragements). A positive bidirectional relation was found between use of common factors techniques and the working alliance, such that initial high levels of common factors (but not prescribed) techniques predicted higher alliance later on and vice versa. CONCLUSION: Therapists tend to modulate their use of common factors techniques across treatment. Additionally, when a strong working alliance is developed early in treatment, therapists tend to use more common factors later on. Moreover, high use of common factors techniques is predictive of later improvement in the alliance.

Psychometric Properties of the Reconstructed Hamilton Depression and Anxiety Scales.

Although widely used, the Hamilton Rating Scale for Depression (HRSD) and Hamilton Anxiety Rating Scale (HARS) discriminate poorly between depression and anxiety. To address this problem, Riskind, Beck, Brown, and Steer (J Nerv Ment Dis. 175:474-479, 1987) created the Reconstructed Hamilton Scales by reconfiguring HRSD and HARS items into modified scales. To further analyze the reconstructed scales, we examined their factor structure and criterion-related validity in a sample of patients with major depressive disorder and no comorbid anxiety disorders (n = 215) or with panic disorder and no comorbid mood disorders (n = 149). Factor analysis results were largely consistent with those of Riskind et al. The correlation between the new reconstructed scales was small. Compared with the original scales, the new reconstructed scales correlated more strongly with diagnosis in the expected direction. The findings recommend the use of the reconstructed HRSD over the original HRSD but highlight problems with the criterion-related validity of the original and reconstructed HARS.

Interpersonal Factors Are Associated with Lower Therapist Adherence in Cognitive-Behavioural Therapy for Panic Disorder.

OBJECTIVE: The contributions of disorder severity, comorbidity and interpersonal variables to therapists' adherence to a cognitive-behavioural treatment (CBT) manual were tested. METHOD: Thirty-eight patients received panic control therapy (PCT) for panic disorder. Trained observers watching videotapes of the sixth session of a 24-session protocol rated therapists' adherence to PCT and their use of interventions from outside the CBT model. Different observers rated patients' behavioural resistance to therapy in the same session using the client resistance code. Interview measures obtained before treatment included the Panic Disorder Severity Scale, the anxiety disorders interview schedule for Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV and the structured clinical interview for DSM-IV, Axis II. Questionnaire measures were the anxiety sensitivity index at intake, and, at session 2, the therapist and client versions of the working alliance inventory-short form. RESULTS: The higher the patients' resistance and the more Axis II traits a patient had, the less adherent the therapist. Moreover, the more resistant the client, the more therapists resorted to interventions from outside the CBT model. Stronger therapist and patient alliance was also generally related to better adherence, but these results were somewhat inconsistent across therapists. Pretreatment disorder severity and comorbidity were not related to adherence. CONCLUSIONS: Interpersonal variables, particularly behavioural resistance to therapy, are related to therapists' ability to adhere to a treatment manual and to their use of interventions from outside of the CBT model. Copyright © 2015 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Patients' behavioural resistance to therapy may make it more difficult for cognitive-behavioural clinicians to adhere to a structured treatment protocol and more likely for them to borrow interventions from outside the CBT model. Patients' Axis II traits may make adherence to treatment CBT protocol more difficult, although whether this is true varies across therapists. Therapists' adherence to a structured protocol and borrowing from outside of the CBT model do not appear to be affected by disorder severity or Axis I comorbidity.

Goldilocks on the couch: Moderate levels of psychodynamic and process-experiential technique predict outcome in psychodynamic therapy.

OBJECTIVES: Greater symptom change is often assumed to follow greater technique use, a "more is better" approach. We tested whether psychodynamic techniques, as well as common factors and techniques from other orientations, had a curvilinear relation to outcome (i.e., whether moderate or "just right" intervention levels predict better outcome than lower or higher levels). METHODS: For 33 patients receiving supportive-expressive psychodynamic psychotherapy for depression, interventions were assessed at Week 4 using the multitheoretical list of therapeutic interventions and symptoms were rated with the Hamilton Rating Scale for Depression. RESULTS: Moderate psychodynamic and experiential techniques predicted greater symptom change compared to lower or higher levels. CONCLUSION: This "Goldilocks effect" suggests a more complex relation of intervention use to outcome might exist.

Therapist-reported alliance: Is it really a predictor of outcome?

Most of the literature on the alliance-outcome association is based exclusively on differences between patient reports on alliance. Much less is known about the unique contribution of the therapist's report to this association across treatment, that is, the association between therapist-reported alliance and outcome over the course of treatment, after controlling for the patient's contribution. The present study is the first to examine the unique contribution of the therapist-reported alliance to outcome, accounting for reverse causation (symptomatic levels predicting alliance), at several time points in the course of treatment. Of 156 patients randomized to dynamic supportive-expressive psychotherapy, antidepressant medication with clinical management, and placebo with clinical management, 149 were included in the present study. Alliance was assessed from the perspective of both the patient and the therapist. Outcome measures included the patients' self-reported and diagnostician-rated depressive symptoms. Overall, the findings demonstrate that the therapists' contribution to the alliance-outcome association was explained mainly by prior symptomatic levels. However, when a time lag of several sessions was introduced between alliance and symptoms, a positive association emerged between alliance at 1 time point and symptomatic distress assessed several sessions later in the treatment, controlling for previous symptomatic level. The findings were similar whether or not we controlled for the patient's perspective on the alliance. Taken together, the findings attest to the importance of improving therapists' ability to detect deterioration in the alliance.

The associations among improvement and alliance expectations, alliance during treatment, and treatment outcome for major depressive disorder.

OBJECTIVE: To examine the associations between treatment/outcome expectations, alliance before and during treatment, and the impact of alliance on symptomatic improvement. METHODS: One hundred and fifty-three depressed patients randomized to dynamic supportive-expressive psychotherapy (SET), antidepressant medication (ADM) or placebo (PBO) + clinical management completed ratings of treatment expectations, therapeutic alliance (CALPAS, WAI-S), and depressive symptoms (HAM-D). RESULTS: Pretreatment expectations of the therapeutic alliance were significantly related to alliance later in therapy but did not differ across treatments and did not predict outcome. Alliance development over time differed between treatments; it increased more in SET than in PBO. After controlling for prior symptom improvement, early alliance predicted subsequent depression change. CONCLUSIONS: Expectations of alliance and of treatment outcome/improvement, measured prior to treatment onset, predicted subsequent alliance.

Therapist contribution, client reflective functioning, and alliance rupture-repair: A microprocess case study of psychodynamic therapy for pregnancy after loss.

Meta-analysis has found a significant relation between rupture-repair and client outcome (Eubanks et al., 2018). Rupture-repair processes may be particularly important in psychotherapy for pregnancy loss wherein ruptures related to client feelings of shame and inadequacy, the societal invalidation of perinatal grief, and reenactments in the therapy relationship of early attachment experiences have been theorized to be common and important events (Markin, 2024). Thus, it is important to understand what occurs on a microlevel during the process of therapy to ultimately explain the rupture resolution (RR) and treatment outcome association. In particular, while both the therapist and client are believed to contribute to ruptures and to their repair (Safran & Muran, 2000), little is known about how therapist contributions impact rupture events, rupture resolution, and treatment progress. Further, client reflective functioning (RF) may represent a set of capacities that contribute to and are increased by rupture resolution yet vary depending on the role of the therapist in the rupture. The current investigation examined how observer-rated therapist contribution to ruptures and client RF were related to rupture events, rupture resolution, and client-reported symptom change and session quality over 22 sessions of psychodynamic therapy for pregnancy after loss. Therapist contribution to ruptures predicted rupture significance, high and steady within-session client RF scores, and symptom change. Client RF and rupture resolution predicted symptom change differently, often depending on type of symptom. Importantly, client RF and rupture resolution may predict successful outcomes through ameliorating commonly reported symptoms during pregnancies after loss.

Efficacy and moderators of short-term psychodynamic psychotherapy for depression: A systematic review and meta-analysis of individual participant data.

BACKGROUND: Short-term psychodynamic psychotherapy (STPP) is frequently used to treat depression, but it is unclear which patients might benefit specifically. Individual participant data (IPD) meta-analyses can provide more precise effect estimates than conventional meta-analyses and identify patient-level moderators. This IPD meta-analysis examined the efficacy and moderators of STPP for depression compared to control conditions. METHODS: PubMed, PsycInfo, Embase, and Cochrane Library were searched September 1st, 2022, to identify randomized trials comparing STPP to control conditions for adults with depression. IPD were requested and analyzed using mixed-effects models. RESULTS: IPD were obtained from 11 of the 13 (84.6%) studies identified (n = 771/837, 92.1%; mean age = 40.8, SD = 13.3; 79.3% female). STPP resulted in significantly lower depressive symptom levels than control conditions at post-treatment (d = -0.62, 95%CI [-0.76, -0.47], p < .001). At post-treatment, STPP was more efficacious for participants with longer rather than shorter current depressive episode durations. CONCLUSIONS: These results support the evidence base of STPP for depression and indicate episode duration as an effect modifier. This moderator finding, however, is observational and requires prospective validation in future large-scale trials.

The Association Between Political Climate and Trainees' Supervision Experiences and Needs.

This study examined whether political climate influenced trainees' clinical work, supervisory experiences, and supervisory alliance. Data were collected from 366 trainees in a nationwide survey. Most trainees believed the political atmosphere affected clients to some degree. Over half reported political dialogue with supervisors, more often when political affiliation was similar. Supervisory alliances were most positive when trainees were aware of their supervisors' political beliefs, regardless of agreement. Trainees wanted supervisors to provide greater awareness of multicultural issues and political climate in their clinical work. We recommend that supervisors invite trainees to discuss political effects on their clinical work.

Beliefs about the causes of depression and treatment preferences.

The relation between patients' beliefs about the causes of their depression, treatment preferences, and demographic variables was studied in a sample of 156 patients in a randomized controlled trial for depression (supportive-expressive psychotherapy vs. medication vs. placebo). No gender differences were found in beliefs or preferences. Racial differences were found for causes endorsed, but not preferences. Treatment experience predicted endorsement of characterological and biological causes. Psychotherapy experience predicted preference for medication. Finally, patients preferring psychotherapy endorsed childhood and complex causes more than those preferring medication, but the groups did not differ in other reasons endorsed. Implications of findings are discussed.

The Personal Norm of Reciprocity among mental health service users: conceptual development and measurement.

OBJECTIVE: A measure of an individual's level of internalization of the norm of reciprocity may signal exchange preferences and indicate whether "active" or "passive" mental health services are preferable to consumers. We evaluated the psychometric properties of one such measure, the Personal Norm of Reciprocity (PNR) scale. METHODS: We recruited 70 persons receiving mental health services and 65 comparison participants to complete questionnaires assessing reciprocity tendencies and correlates of mental illness. RESULTS: Two of three subscales of a shortened PNR showed evidence of reliability and validity. Consumers endorsed higher levels of the reciprocity norm than persons not seeking services. Persons in "active" service settings displayed greater rigidity in application of the reciprocity norm than individuals in "passive" service settings or comparison participants. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The shortened PNR can be a useful measure of individual reciprocity preferences. Measurement of the internalization of the norm of reciprocity may assist practitioners in identifying what types of services are more likely to retain and benefit mental health service consumers.

Isolated sleep paralysis and fearful isolated sleep paralysis in outpatients with panic attacks.

Isolated sleep paralysis (ISP) has received scant attention in clinical populations, and there has been little empirical consideration of the role of fear in ISP episodes. To facilitate research and clinical work in this area, the authors developed a reliable semistructured interview (the Fearful Isolated Sleep Paralysis Interview) to assess ISP and their proposed fearful ISP (FISP) episode criteria in 133 patients presenting for panic disorder treatment. Of these, 29.3% met lifetime ISP episode criteria, 20.3% met the authors' lifetime FISP episode criteria, and 12.8% met their recurrent FISP criteria. Both ISP and FISP were associated with minority status and comorbidity. However, only FISP was significantly associated with posttraumatic stress disorder, body mass, anxiety sensitivity, and mood and anxiety disorder symptomatology.

Randomized Controlled Trial of a Novel Peer Concussion-Education Program for Collegiate Athletes.

CONTEXT: The National Collegiate Athletic Association and US Department of Defense have called for educational programs to change the culture of concussion reporting, increase reporting behavior, and enhance the safety of players and service members. OBJECTIVE: To evaluate the effects of a novel peer concussion-education program (PCEP) in changing knowledge, attitudes, and norms about concussion reporting among collegiate student-athletes and assess program implementation. DESIGN: Randomized controlled trial and qualitative analysis of interviews. SETTING: National Collegiate Athletic Association athletic teams from randomly selected colleges or universities. PATIENTS OR OTHER PARTICIPANTS: A total of 1614 male and female student-athletes from 60 teams at 10 colleges and universities and 8 athletic trainers. INTERVENTION(S): The PCEP intervention trains 2 peer concussion educators to provide 2 education modules to their teammates. Knowledge, attitudes (oneself and teammates), and concussion occurrence or reporting were assessed at baseline, postintervention, and 1 month later. Eight athletic trainers were interviewed about program implementation. RESULTS: Compared with the control group, the intervention group showed greater increases occurred postintervention and at 1 month in concussion knowledge (F1,2648 = 51.3, P < .0001), intention to report (oneself, F2,2633 = 82.3, P < .0001; teammates, F2,2624 = 53.9, P < .0001), return-to-play protocol knowledge, (F2,2632 = 28.4, P < .0001), direct subjective norms (oneself, F2,2625 = 51.7, P < .0001; teammates, F2,2644 = 40.6, P < .0001), direct perceived behavioral control (oneself, F2,2628 = 53.7, P < .0001; teammates, F2,2615 = 68.2, P < .0001), and indirect attitudes (oneself, F2,2626 = 47.1, P < .001; teammates, F2,2623 = 40.9, P < .0001). Peer concussion-education program participants discussed concussion more often with a teammate (F1,1396 = 13.96, P < .0001) or athletic staff (F1,1396 = 6.62, P < .001). Qualitative program analysis revealed both positive aspects of the PCEP and areas for improvement. CONCLUSIONS: The PCEP showed promise in increasing concussion knowledge, intention to report concussion, reporting a teammate's concussion, and facilitating attitudinal changes that support reporting among student-athletes.
