Altman Self-Rating Mania Scale   (ASRM; Altman, Hedeker, Peterson, & Davis, 1997).   The ASRM is a 5-item self-report measure assessing mania symptoms in adults.  The ASRM can be used as a screening tool (Altman et al., 1997), and to monitor symptom changes over time (Altman, Hedeker, Peterson, & Davis, 2001). A version of the ASRM for adolescents exists as an "emerging measure" from section III of the DSM-V (Diagnostic and Statistic Manual of Mental Disorders, 5 th edition, American Psychiatric Association, 2013). Sample statements include, “I feel happier or more cheerful than usual all the time” and “I am constantly active or on the go all the time.” Respondents choose a statement from a group of items that are rated on a 5-point scale from zero to four that best fit how they have been feeling in the past week. Total scores range from 0 to 16. The ASRM demonstrates adequate internal consistency ( α = 0.79), and adequate test-retest reliability over a period of 2.

Sick, Control, One, Fat, Food Screening Tool (SCOFF) Morgan, Reid, & Lacey, 1999 The SCOFF is a 5-item self-report measure assessing eating concerns in adults. The SCOFF can be used as a screening tool (Luck et al., 2002). The SCOFF has been used in studies with adolescents (Hautala et al., 2008;) but does not include a separate adolescent version. Sample items include, “Do you make yourself sick because you feel uncomfortably full” and “Would you say food dominates your life?” Each item is a “yes” or “no” question, with two or more endorsements indicating a “likely” case of AN or BN (Morgan et al., 1999). This assessment is designed for use by non-specialists to screen for eating concerns. An individual scoring a two or higher should seek an evaluation by a qualified professional. The SCOFF demonstrates good concurrent validity, detecting diagnoses of AN and BN as determined by the DSM-IV with 100% sensitivity and 87.5% specificity (Hill, Reid, Morgan, & Lacey, 2010). The SCOF

Eating Disorder Diagnostic Scale (EDDS) Stice, Telch, & Rizvi, 2000) The EDDS is a 22-item self-report measure assessing symptoms of anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) in adults.  The EDDS can be used as a screening tool a diagnostic tool, and to monitor symptom changes over time. The EDDS was developed with a population partially of adolescents and does not include a separate adolescent version. Sample items include, “Have you felt fat?” and “Has your weight influenced how you think about (judge) yourself as a person?”  Items are rated on a variety of scales including zero (“not at all”) to six (“extreme”) for items about feelings related to gaining weight, “yes” or “no” questions for items related to different eating disorders experiences, frequency ratings for items related to average eating behaviours, and questions related to the physical symptoms of eating disorders. Items encompass the Diagnostic and Statistical Manual of Mental Diso

Patient Health Questionnaire-9 (PHQ-9) Kroenke, Spitzer, & Williams, 2001 The PHQ-9 is a 9-item self-report measure assessing depressive symptoms in adults.  The PHQ-9 can be used as a screening tool a diagnostic tool, and to monitor symptom changes over time. There exists a separate version of the PHQ-9 for adolescents within the Patient Health Questionnaire-Adolescent Version (PHQ-A; Johnson et al., 2002). Sample items include, “ Little interest or pleasure in doing things” and “Feeling down, depressed, or hopeless.” Each item is rated on a scale from zero (“not at all”) to three (“nearly every day”). Total scores range from 0-27. Meta-analysis of the PHQ-9 diagnostic accuracy compared to independent mental health professional diagnosis demonstrates good criterion validity with a sensitivity of 77% and a specificity of 94%.   The PHQ is also validated as an 8- and 2-item measure to assess depression severity. The measures are available online (Stable Resource Toolkit, SAMHSA, 19

The Inventory of Depressive Symptoms and the Quick Inventory of Depressive Symptoms (IDS and QIDS)   Rush et al., 1986; Rush, Gullion, Basco, Jarrett, & Trivedi, 1996; Rush et al., 2003). T he IDS/QIDS can be used as a screening tool; the QIDS is also appropriate to use as a diagnostic tool and to monitor symptom change over time (IDS-QIDS.org, 2013). The IDS/QIDS has not been used with adolescents, nor does a separate adolescent version exist. The IDS (30-item) and QIDS (16-item) are self- and clinician-report measures assessing depressive symptoms in adults. The briefer QIDS queries for only the nine major depressive disorder domains outlined in the Diagnostic and Statistical Manual of Mental Disorders 4 th ed, Text Revision (DSM-IVTR, American Psychiatric Association, 2010), where the IDS queries for these domains as well as associated symptoms such as anxiety and irritability. Each item is rated from zero (“does not feel sad”) to three (“feels intensely sad virtually all the t

Hamilton Rating Scale for Depression (HAM-D) Hamilton, 1960. The HAM-D is a 17-item clinician-report measure assessing depressive symptoms in adults. The HAM-D can be used as a screening tool (Hamilton, 1960). There is disagreement in the literature regarding the HAM-D’s sensitivity to change and thus its appropriateness as a treatment monitoring tool. The HAM-D has been used in several studies with adolescents (e.g. Keller et al., 2001), but a separate adolescent version does not exist. Sample items include, “Depr e ssed mood” and “Feelings of guilt.” Eight symptoms are scored by severity on a zero to four scale, and eight symptoms are scored by intensity on a zero to two scale. The HAM-D is designed to be administered in 12 minutes and a structured interview guide can assist in scoring. The HAM-D demonstrates good internal consistency (α = .83), and adequate test-retest reliability over a period of four days ( r = .81). It demonstrates good to excellent inter-rater reliability (ICC

The Clinically Useful Depression Outcome Scale (CUDOS) (Zimmerman, Chelminski, McGlinchey, & Posternak, 2008) The CUDOS can be used as a screening tool, a diagnostic tool (Zimmerman et al., 2008), and to monitor symptom changes over time (Zimmerman, McGlinchey, & Chelminski, 2008). The CUDOS has not been used with adolescents, nor does a separate adolescent version exist. The CUDOS is an 18-item self-report measure assessing depressive symptoms in adults. Sample items include, “I felt sad or depressed,”  “I was not as interested in my usual activities,” and “I felt guilty.” Each item is rated on a 5-point Likert scale indicating from zero (“not at all true/0 days”) to four (“almost always true/every day”). Total scores range from 0 to 64. The CUDOS was designed to be completed in less than three minutes and scored in less than 15 seconds. The CUDOS demonstrates excellent internal consistency (α = .90) and adequate test-retest reliability over a period of one week ( r > .92;

Worry and Anxiety Questionnaire Worry and Anxiety Questionnaire (WAQ; Dugas et al., 2001). The WAQ is an 11-item self-report measure assessing GAD symptoms in adults. The WAQ can be used as a screening and diagnostic tool (Dugas, Freeston, Lachance, Provencher, & Ladouceur, 1995), and to monitor symptom change over time (Dugas et al., 2003). The WAQ has not been used with adolescents, nor does a separate adolescent version exist. The WAQ consists of two subscales: cognitive and somatic. All items are rated on a 9-point Likert scale from zero (“less severity/greater function”) to eight (“increased severity/low functioning”). The WAQ can identify whether individuals meet none of the criteria for GAD, the somatic criteria only, or all of the criteria for GAD (Buhr & Dugas, 2002). The WAQ demonstrates adequate test-retest reliability over a period of four weeks ( r = .76; Buhr & Dugas, 2002)). It also demonstrates good content validity and constructs validity (Hunsley & Mas

Social Phobia Inventory (SPIN) Connor et al., 2000 The SPIN is a 17-item self-report measure assessing social phobia symptoms in adults.  The SPIN can be used as a screening tool to monitor symptom change over time (Connor et al., 2000). The SPIN has been used in several studies with adolescents (e.g. Johnson, Inderbitzen-Nolan, & Anderson, 2006) and a brief version exists (MINI-SPIN, Connor, Kobak, Churchill, Katzelnick, & Davidson, 2001), also valid for adolescents (Ranta, Kaltiala-Heino, Rantanen, & Marttunen, 2012). The SPIN consists of three subscales: fear, avoidance, and physiological discomfort. Example items include, “Being embarrassed or looking stupid are among my worst fears,” “I avoid talking to people I don’t know,” and “I am bothered by blushing in front of people.” Items are scored from zero (“not at all”) to four (“extremely”). A cutoff value of 19 demonstrates diagnostic accuracy of 79% (Connor et al., 2000). The SPIN demonstrates adequate test-retest reli

Penn State Worry Questionnaire Penn State Worry Questionnaire (PSWQ; Meyer, Miller, Metzger, & Borkovec, 1990). The PSWQ is a 16-item self-report measure assessing worry associated with Generalized Anxiety Disorder (GAD) in adults. The PSWQ can be used as a screening tool (Trull & Hillerbrand, 1990), and, in the case of the weekly version, to monitor symptom change over time (PSWQ-Past Week; Stöber & Bittencourt, 1998). A version of the PSWQ for children and adolescents exists (PSWQ-C; Chorpita, Tracey, Brown, Collica, & Barlow, 1997) and is included in our child appendix. Sample items include, “My worries overwhelm me” and “If I do not have enough time to do everything, I do not worry about it.” Each item is rated on a 5-point scale from one (“not at all typical of me”) to five (“very typical of me”). The PSWQ can be administered in a few minutes, and scoring is simple. The PSWQ demonstrates excellent internal consistency (α = .94) and adequate test-retest reliabilit
