ADHD is one of the most common referral reasons for neuropsychological evaluation with an estimated prevalence of 4.4% in adults.

Participants and Methods: Participants included outpatients who were referred for a focused neuropsychological evaluation for diagnostic clarification and treatment planning related to possible ADHD (N = 498). All patients completed the MMPI-2-RF, Clinical Assessment of Attention Deficit-Adult (CAT-A), a semi-structured clinical interview, and uniform neuropsychological test battery as part of their clinical evaluation. Patients with definite invalid MMPI-2-RF profiles based on standard validity scale cutoffs were excluded. The sample mean age was 28.62 years (SD = 7.23) with a mean of 16.03 years of education (SD = 2). 60.8% were female, and 53.8% were from minority racial/ethnic groups. Internalizing psychopathology was assessed by examining the MMPI-2-RF internalizing psychopathology scales (RCd, RC2, and RC7) and psychopathology groups were created based on those with 0 vs ≥1 elevations on these three scales.

A multivariate analysis of variance (MANOVA) was conducted to assess differences in severity of ADHD symptoms between groups with 0 vs >1 elevations on the MMPI-2-RF internalizing psychopathology scales. Results: There was a significant difference between groups on ADHD symptom reporting [F(3, 494) = 6.138, p < .001, Wilk’s lambda = .964, np² = .036]. Follow up one-way ANOVAs revealed that those with elevated internalizing symptoms had significantly higher Current Symptoms of ADHD [F(1,496) = 11.997, p =.001, np²= .024] and Total Clinical Index score [F(1,496) = 4.625, p = .032, np²= .009], but not childhood ADHD symptoms [F(1,496) = .493, p = .483, np²= .001]. Conclusions: Findings suggest that patients with elevations on the internalizing psychopathology scales of the MMPI-2-RF endorse more severe current ADHD symptoms, but not childhood ADHD symptoms.

Objective:

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition characterized by inattentiveness, hyperactivity, and impulsivity. ADHD is one of the most common referral reasons for neuropsychological evaluation with an estimated prevalence of 4.4% in adults. Additionally, individuals with ADHD commonly present with co-occurring psychiatric conditions (e.g., depression, anxiety, substance use). Existing literature suggests that adults with ADHD and no co-occurring conditions produce relatively unremarkable Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) profiles aside from elevations on the Cognitive Complaints (COG) scale. As such, the MMPI-2-RF may be particularly useful for differentiating individuals with ADHD alone from those with co-occurring psychopathological conditions that may be exacerbating ADHD-related symptom complaints (e.g., inattention). The present study explored the degree to which symptoms of internalizing psychopathology endorsed on the MMPI-2-RF are associated with ADHD symptom reporting.

Participants and Methods:

Participants included outpatients who were referred for a focused neuropsychological evaluation for diagnostic clarification and treatment planning related to possible ADHD (N = 498). All patients completed the MMPI-2-RF, Clinical Assessment of Attention Deficit-Adult (CAT-A), a semi-structured clinical interview, and uniform neuropsychological test battery as part of their clinical evaluation. Patients with definite invalid MMPI-2-RF profiles based on standard validity scale cutoffs were excluded. The sample mean age was 28.62 years (SD = 7.23) with a mean of 16.03 years of education (SD = 2). 60.8% were female, and 53.8% were from minority racial/ethnic groups. Internalizing psychopathology was assessed by examining the MMPI-2-RF internalizing psychopathology scales (RCd, RC2, and RC7) and psychopathology groups were created based on those with 0 vs ≥1 elevations on these three scales. ADHD symptoms were assessed in childhood and adulthood using the CAT-A. A multivariate analysis of variance (MANOVA) was conducted to assess differences in severity of ADHD symptoms between groups with 0 vs >1 elevations on the MMPI-2-RF internalizing psychopathology scales.

Results:

There was a significant difference between groups on ADHD symptom reporting [F(3, 494) = 6.138, p < .001, Wilk’s lambda = .964, np² = .036]. Follow up one-way ANOVAs revealed that those with elevated internalizing symptoms had significantly higher Current Symptoms of ADHD [F(1,496) = 11.997, p =.001, np²= .024] and Total Clinical Index score [F(1,496) = 4.625, p = .032, np²= .009], but not childhood ADHD symptoms [F(1,496) = .493, p = .483, np²= .001].

Conclusions:

Findings suggest that patients with elevations on the internalizing psychopathology scales of the MMPI-2-RF endorse more severe current ADHD symptoms, but not childhood ADHD symptoms. As a result, clinical implications include consideration of internalizing psychopathology when working with patients with possible ADHD to ensure appropriate recommendation (e.g., evidence based treatment such as cognitive behavioral therapy) following neuropsychological evaluation.
