The Utility of the CVLT-C as an Embedded Validity Indicator After Pediatric Mild Traumatic Brain Injury.

Results of neuropsychological examinations depend on valid data. Whereas clinicians previously believed that clinical skill was sufficient to identify non-credible performance by examinees on standard tests, research demonstrates otherwise. Consequently, studies on measures to detect suspect effort in adults have received tremendous attention in the previous twenty years, and incorporation of validity indicators into neuropsychological examinations is now seen as integral. Few studies exist that validate methods appropriate for the measurement of effort in pediatric populations. Of extant studies, most evaluate standalone measures originally developed for use with adults. The present study examined the utility of indices from the California Verbal Learning Test – Children's Version (CVLT-C) as embedded validity indicators in a pediatric sample. Participants were 225 outpatients aged 8 to 16 years old referred for clinical assessment after mild traumatic brain injury (mTBI). Non-credible performance (n = 39) was defined as failure of the Medical Symptom Validity Test (MSVT). Logistic regression demonstrated that only the Recognition Discriminability index was predictive of MSVT failure (OR = 2.88, p < .001). A cutoff of z ≤ -1.0 was associated with sensitivity of 51% and specificity of 91%. In the current study, CVLT-C Recognition Discriminability was useful in the identification of non-credible performance in a sample of relatively high-functioning pediatric outpatients with mTBI. Thus, this index can be added to the short list of embedded validity indicators appropriate for pediatric neuropsychological assessment.

Phototherapy as an Intervention in Identity Development with Adolescents.

Identity development in adolescence is a period of exploration and experimentation. During this stage of development, adolescents are defining their identity in terms of ethnicity, sexual orientation, and gender. It can be a confusing time and the lack of resources and support influence the ability of the adolescent to form a cohesive identity. This struggle to define an identity may lead to symptoms of depression and difficulties with interpersonal relationships. Identity interventions are limited and primarily involve the adolescent talking to a therapist and attempting to verbalize and define subjective distress. The use of a phototherapy intervention focuses on using an adolescent's subjective experiences. Phototherapy provides a way for the therapist and client to explore the photographs the client takes and opens different avenues in the areas of non-verbal and visual communication. Photographs can also promote increased communication about an adolescent's ethnic, sexual or gender identity. Interpretations made by the adolescent about images in the photographs will get in touch with emotional experiences that may be missed in traditional "talk therapy." This paper reviews literature on identity development, specifically in the areas of ethnicity, sexual orientation, and gender identity. Phototherapy, the use of photography to enhance traditional psychotherapy, is described and a rationale is provided for the utilization of phototherapy in adolescent identity development. Vignettes are provided illustrating how phototherapy can be used when working with adolescents who are questioning and exploring ethnic identity, sexual orientation, and gender identity.
