INSTRUCTIONS

Overview: The Pediatric Anxiety Rating Scale (PARS) is to be used to rate the severity of anxiety in children and adolescents, ages 6 to 17 years. The PARS has two sections: the symptom checklist and the severity items. The symptom checklist is used to determine the child’s repertoire of symptoms during the past week. The 7-severity item is used to determine severity of symptoms and the PARS total score.

Symptoms include in the rating are commonly observed in patients with the following disorder, panic disorder and specific phobia. Obviously, there is considerable overlap in symptoms among these anxiety disorders. Symptoms specific to obsessive compulsive disorder and post traumatic stress disorder are not included.

The time frame for the PARS rating is the past week. Only those symptoms endorsed for the past week are included in the symptom checklist and rated on the severity items.

The respondents should be the same for each rating on the same subject. For example, in a treatment trial, where the PARS may be administered multiple times to the same child, it is important that the same primary caregiver (e.g., mother) be present at each rating. If both parents are present for the first rating, both should be present for subsequent ratings.

The format of the interview: The goal of the interview is to elicit as much information as possible about the child’s level of anxiety. To achieve this goal, it is necessary to obtain information from both the child and the primary caregiver (at least). The clinician combines all information from all informants to make the ratings.

Usually, for pre-teens, the interviewer starts with the parent(s) alone and subsequently interviews the child alone. For teenagers, the reverse order is generally preferred (adolescent first, followed by the parent(s)). With some families, it may be preferable to interview the child and parent(s) together. Both should be told in advance that they will have an opportunity, if indicated, to speak alone with the interviewer. The order and procedure for interviews should remain constant throughout multiple ratings.

Symptom Checklist: The symptom checklist is the first of the two major sections of the PARS. The goal of the checklist is to document the array of the patient’s symptoms that will be used to establish severity during the ratings of severity items. Thus, the symptom checklist is not to be used to establish severity.

Use items as probes to elicit the patient’s complete symptom repertoire. Elicit information from both child and parent(s). Use your best judgement to combine information from all informants. Remember, symptoms occurring during the past week only are to be recorded.

Severity Ratings: Using all of the symptoms endorsed for the past week, rate severity of symptoms for each of the 7 severity items. Use the anchors for each item to assist the child and parent in establishing severity. Respondents may wonder whether the severity items are rating an average for the past week, or the worst day, or worst time, etc. The severity items are meant to elicit information about average symptom severity over the past week. Record all scores in whole numbers; in-between scores (e.g., 1.5) are not permitted.

Follow-up Evaluations: Eliciting information about the symptom lisst can be much more efficient during subsequent ratings of the same subject. The interviewer can use the symptom checklist from the prior rating as a guide. For a follow-up rating, the interviewer can describe to the subject the symptoms that were endorsed at the prior rating. Then the interviewer asks if there have been any new symptoms during the past week. Finally, the interviewer uses the probes to be sure that no symptoms have been overlooked. However, since the subject will be familiar with the probes from prior assessments, the probes can be reviewed rapidly, with the expectation that they will not be endorsed.

Scoring: The total score for the PARS is total of the 7 severity items. The total score ranges from 0 to 35. (Codes “8” and “9” are not included in the summation.) For clinical trials, severity is based on the sum of items #2,3,5,6, and 7.

Sample Probes for the Symptom List: Social interactions or performance situations: During the past week, have you (has s/he) worried about or avoided social situaitons? Let me give you some examples (refer to list). During the past week, have you (has s/he) been shy about or refused to do things in public? Let me give you some more examples.

Separation Anxiety: Some children worry about being away from their mother or father. What about you (your child)? Some children do things to make sure they stay near their mother or father? What about you (your child)? Let me give you examples.

Generalized Anxiety: Some people worry about a lot of different things. What about you (your child)? What about during the past week? Let me give you some examples.

Specific Phobia: Do you worry about or have fears of animals (e.g. dog), etc?

Physical Signs/ Symptoms: Sometimes children notice feelings or changes in their bodies when they are anxious or worried? What about you? Let me give examples.
