Multiphasic Sex Inventory II - Adolescent Male Form
The MSI II Adolescent Male Form is designed to measure the sexual characteristics of an adolescent male
(12 to 19 years old) alleged to have committed a sex offense or sexual misconduct and can be used both to do a
sex deviance evaluation and also to measure treatment progress. It can be useful in evaluation a client who
has been alleged to have engaged in sexual misconduct but who denies any such behavior. This form should not
be used with 12 or 13 year old clients unless they admit committing a sex offense or misconduct.
Description and Scales
The MSI II Adolescent Male Form has been derived from the work done on the Adult Male Form. Several scales
have been developed to assess a subjects response set (reliability / validity). There are four primary paraphilias
measured and several secondary paraphilias. There are scales to assess Emotional Eeediness, Cognitive Disorder,
Gender Identity, Social Sexual Inadequacies and Sex Knowledge and Beliefs. There are five behavioral scales including
Conduct Disorder, Aggressive Behavior, Substance Abuse, Attention Deficit / Hyperactivity Disorder and Oppositional
Defiant behavior. There are four accountability scales, a treatment history and treatment attitudes measures and,
like the adult form, there is a brief social / sexual history of each client.
The MSI II Adolescent Male Form data has been gathered from a wide geographic area which includes Idaho,
Washington, Oregon, Texas, Arizona, California, Utah, Georgia, North Carolina, South Carolina, Minnesota,
Illinois, Maine, New Jersey and Virginia. The sample of 775 adolescents includes 460 child molesters, 100 rapists,
40 exposers, 75 end of treatment child molesters and 100 non admitting sex offenders. Their ages ranged from 11
to 20 years and 78% were White, 12% Hispanic and 10% Black. Seventy-three percent were community based and the
remaining 27% were from inpatient treatment centers.
The scales were normed and findings compared with the scale results from the MSI II Adult Male Form samples.
Coefficient alphas range from rtt = .65 to .89 for most of the major scales with the smaller indices (5 to 8 items)
showing less homogeneity.
Form of Test
The MSI II Adolescent Male Form is a paper and pencil test with 559 true/false questions and takes approximately
90 minutes for the client to take. It requires approximately a 7th grade reading level, however, a cassette tape of
the questions is available for use by those clients who have reading difficulties. All forms of the MSI II
must be sent to Nichols & Molinder Assessments, Inc. for scoring and interpretation. The scoring information is
placed on a concise (four page) profile form designed for ease in use by
While the Multiphasic Sex Inventory II Clinician's Handbook was developed for the Adult Male Form, it is useful
in understanding the Adolescent Male Form as well.
The MSI II Adolescent Male Form is only available in English and has not been translated into any other
While the MSI II may not be available for clinicians to score and interpret on their own for some time,a test
scoring and interpretation service is presently available for those qualified clinicians who wish to begin taking
advantage of the enhancements included in the MSI II. A clinician tests the client in their setting and sends
the completed answer sheets to Nichols & Molinder Assessments, Inc. The results are then sent back as a 2 to 4 page
report of the findings and a comprehensive four page profile form that can be used
in a clinical interview, report writing, treatment planning, assessing treatment progress etc. For information on
