Excessive anxiety among elementary students is highly prevalent and associated with impairment in academic, social, and behavioral functioning. The primary aim of this project is to evaluate the initial efficacy of a brief nurse-delivered intervention (CALM: Child Anxiety Learning Modules), relative to a credible comparison (CALM-R, relaxation skills only) and a waitlist control for reducing anxiety symptoms and improving education outcomes at post intervention and at a 1-year follow-up. In addition, the research team will assess the cost effectiveness of CALM versus CALM-R and the waitlist control and examine potential predictors, moderators, and mediators of CALM's impact on child outcomes based on the proposed theory of change.
Excessive anxiety among elementary age students is common, severely impairs academic, social, and behavioral functioning, and is associated with significant educational and health care costs. Despite the high burden of anxiety, less than half of children with anxiety receive the services they need to succeed in school. School clinicians can and do support these youth, however, their caseloads are high and their time to provide individualized services is limited. Consequently, there is a critical need to expand the network of providers who can assist students with anxiety and address this malleable obstacle to student academic success. Because somatic complaints, such as headaches and stomach aches, are a hallmark feature of excessive anxiety, school nurses are often the first school-based personnel to identify problematic anxiety in students. However, school nurses currently lack training in evidenced-based anxiety reduction interventions. The current study leverages findings from a three-year IES Development award (R305A140694), through which our team developed and assessed the feasibility of training elementary school nurses to use a brief intervention to reduce student anxiety; it was demonstrated that the training and intervention (i.e., Child Anxiety Learning Modules; CALM) was indeed feasible to implement and resulted in positive changes in student outcomes. CALM is now a fully developed intervention with ready-to-use intervention components and materials, training and coaching procedures, and is ready for an initial efficacy evaluation in authentic school settings. Toward that end, the primary purpose of this study is to evaluate the efficacy of CALM in a fully powered randomized controlled trial. CALM will be delivered by elementary school nurses in rural, suburban, and urban elementary schools nationwide to enhance the generalizability of findings across socioeconomic, racial, ethnic, and neighborhood settings (as approximately 80% of schools in the US have a school nurse). The efficacy of CALM will be tested using gold standard methods (e.g., independent evaluators to assess primary outcomes). The study's primary aim is to evaluate the efficacy of CALM, compared to a credible comparison condition (CALM-R; a school nurse delivered relaxation skills only intervention that parallels CALM in time and format) as well as a waitlist control, for reducing anxiety symptoms and improving educational outcomes at post-intervention and a one year follow-up. The secondary aim is to examine the cost effectiveness of CALM relative to CALM-R and the waitlist control. An exploratory aim is to examine potential predictors, moderators, and mediators of student outcomes based on the proposed theory of change. If efficacious, CALM will be the first evidenced-based school nurse delivered intervention to assist youth with excessive anxiety, filling an important gap in current practices.

CALM is a cognitive-behavioral intervention for childhood anxiety. CALM consists of five modules. The primary components include psychoeducation, relaxation training (C), behavioral exposure (A), cognitive restructuring (L), and relapse prevention (M). There is also an optional parent psychoeducation module. Students randomized to the CALM condition will receive the 5 modules over 8 weeks.
CALM-R serves as an active comparison condition to CALM and consists of 5 modules of relaxation skills. The key components of CALM-R include psychoeducation, deep breathing, progressive muscle relaxation, guided imagery, and relapse prevention. Students randomized to the CALM-R condition will receive the 5 modules over 8 weeks.

The CGI-I provides a global rating of improvement in anxiety, relative to baseline. The measure yields a single rating of clinical improvement during the past week, relative to the baseline rating. Scores range from 1 (very much improved) to 7 (very much worse).
Time frame: 8 weeks after baseline
Clinical Global Impression - Impairment (CGI-I) Scale, 12-month follow-up
The CGI-I provides a global rating of improvement in anxiety, relative to baseline. The measure yields a single rating of clinical improvement during the past week, relative to the baseline rating. Scores range from 1 (very much improved) to 7 (very much worse).
Time frame: 12-month follow-up
Children's Somatization Inventory (CSI-24)
The CSI-24 is a is 24-item child- and parent-report measure of the child's somatic symptoms. Parents and children respond to the items using a 5-point scale ranging from "not at all" to "a whole lot." One total score calculated by summing the items. Items are scored 0-4 (range: 0-96); higher scores reflect higher levels of subjective severity of somatic symptoms.
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Behavioral Avoidance
The Behavioral Avoidance form is a 3-item measure assesses how frequently the student avoids specific anxiety provoking situations. The independent evaluator creates a list of the top 3 anxiety-provoking situations and estimates the frequency with which the child avoids those situations over a two week period prior to evaluation. Avoidance for each situation is measured on a 7-point Likert scale, ranging from 1 (never avoid) to 7 (avoid every time).
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Children's Automatic Thoughts Scale (CATS)
The CATS is a 40-item measure that assesses frequency of students' maladaptive thoughts associated with anxiety. Children respond to items using a 5-point Likert-type scale describing the frequency with which they have had various thoughts over the past week (not at all, sometimes, fairly often, often, all the time). Higher scores reflect greater frequency of negative self-statements. Three scores are derived from the CATS: one total score (20 items, score range 0-80) plus two subscale scores reflecting the content of self-statements: physical threat (10 items, score range 0-40), social threat (10 items, score range 0-40).
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Children's Global Assessment Scale (CGAS)
The CGAS is a rating scale that indicates a child's global functioning on a scale of 1 (lowest) to 100 (highest). In general, scores below 70 are indicative of increasingly severe impairment in functioning.
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up

Subtests from the Woodcock-Johnson Tests -Achievement and Cognitive Batteries (WJ IV)
Subtests from the WJ-IV (i.e., reading, math fluency, and digits backwards) will be administered by the IE to measure cognitive factors (e.g., efficiency, speed, working memory) that are believed to be affected by anxiety. Standard scores will be derived for the Reading Sentences Fluency, Math Facts Fluency, and Numbers Reversed subtests. Standard scores reflect the following ability level: \<69=very low; 70-79=low; 80-89=low average; 90-110=average; 111-120=high average; 121-130=superior; \>131=very superior.
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Strength and Difficulties Questionnaire (SDQ), Teacher and Parent Versions
The SDQ assesses a range of emotional and behavioral difficulties in children 4-17 years old (e.g., conduct problems, hyperactivity/ inattention, peer relationship problems, and prosocial behaviors). Nine scores can be derived from the SDQ. (1-5) Five subscales, each of which corresponds to 5 domains: emotional symptoms, conduct problems, hyperactivity, peer problems, prosocial problems. Subscale scores are summed. (6) The total score is generated by summing the scores from all the scales except the prosocial scale. (7-8) Externalizing scores (conduct and hyperactivity) and internalizing scores (emotional and peer problems) are also provided. (9) The impact score is a sum of questions reflecting distress and impairment. Subscale scores each range from 0-10. Externalizing and internalizing scores range from 0-20. The total score can range from 0 to 40. The impact score ranges from 0-6. Higher scores indicate higher levels of the behavior in question.
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Teacher Observation of Classroom Adaptation-Checklist Concentration subscale (TOCA-C)
The TOCA-C concentration subscale is a 7-item subscale of the TOCA that assesses teachers' perceptions of a student's classroom concentration problems. Teachers rate student concentration on a 6-point Likert scale that ranges from "never (1)" to "almost always (6)." Only the Concentration Problems subscale is used in this study. This subscale includes 7 items (range = 7-42). Higher scores on indicate more maladaptive behaviors.
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Academic Competence Evaluation Scale (ACES), short version
The ACES is a 32-item teacher report measure that assesses classroom skills and behaviors. Each item is rated on a 5 point scale (1 = never, 5= almost always), with the option to indicate that the behavior is not observed (N/O). The measure is divided in 2 main scales: Academic Skills (14, score range 0-70), consisting of Reading/Language Arts (6 items, score range 0-30), Mathematics (4 items, score range 0-20), and Critical Thinking (4 items, score range 0-20); Academic Enablers (18 items, score range 0-90), consisting of Motivation (5 items, score range 0-25), Engagement (4 items, score range 0-20), Study Skills (4 items, score range 0-20), and Interpersonal Skills (5 items, score range 0-25). Higher scores reflect higher abilities.
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Child Anxiety Impact Scale (CAIS)
The CAIS is a 27-item child- and parent-report measure of anxiety-related interference in social, academic and family functioning. Children and parents respond to items using a 4-point Likert scale (not at all, just a little, pretty much, very much); higher scores represent greater interference of anxiety in child functioning. The CAIS-C has a total score (27 items, score range 0-81) and three subscales: school (10 items, score range 0-30), social (11 items, score range 0-33), and home/family (6 items, score range 0-18).
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
School Anxiety Scale - Teacher Report (SAS-TR)
The SAS is a 16-item teacher questionnaire that assesses anxiety in the school setting, with a specific focus on social and generalized anxiety symptoms relevant to classroom participation. Teachers rate student anxiety on a 4-point Likert scale that ranges from "never (0)" to "always (3)." The SAS-TR contains a total score (16 items, range of 0 to 48) and two subscales: social anxiety (7 items, range of 0-21) and generalized anxiety (9 items, range of 0 to 27). Higher scores represent higher levels of anxiety; scores of 8 and more on the social anxiety, 10 or more on the generalized anxiety, and 17 or more on the total anxiety is considered to represent high anxious condition.
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Clinical Global Impression - Severity (CGI-S) Scale
The CGI-S provides a global rating of anxiety severity. The measure yields a single rating of anxiety symptom severity during the past week. Scores range from 1 (Normal; Not at all ill) to 7 (Extremely ill)
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Anxiety Disorders Interview Schedule for DSM-V, Parent and Child Versions (ADIS-V)
The ADIS-V is a structured interview that assesses anxiety diagnoses and severity in youth. Impairment ratings are generated for each diagnosis using the Clinician Severity Rating (CSR, range = 0-8; higher CSRs indicate higher severity of anxiety disorders, a CSR of 4 is required to assign a diagnosis). Diagnoses are derived separately from the child and parent report, which yields a Composite Diagnosis that is one measure used to determine study eligibility.
Time frame: Baseline, 8 weeks after baseline, 12-month follow-up
Screen for Child Anxiety-Related Emotional Disorders (SCARED), parent and child versions
The SCARED is a 41-item child- and parent-report measure of anxiety. Youth and parents respond to items using a 3-point Likert-type scale describing the degree to which statements are true (0 = not true or hardly ever true, 1 = somewhat true or sometimes true, 2 = very true or often true). Higher scores represent higher levels of anxiety. Six scores can be derived from the SCARED: one total score (41 items, score range 0-82) plus five subscale scores: panic/somatic (13 items, score range 0-26), generalized anxiety (9 items, score range 0-18), (3) separation anxiety (8 items, score range 0-16), social anxiety (7 items, score range 0-14), and school phobia (4 items, score range 0-8).
