FTODMHI reports Mental Health Indicator (MHI) scores for female sample children age 2 to 3 based on parents' responses to a set of four questions about behavioral/emotional problems. The questions used to calculate MHI scores were taken from the Child Behavior Checklist (CBCL) developed by Dr. Thomas Achenbach and were selected separately according to specific gender and age groups (males and females; ages 2-3, 4-11, 12-17).
FTODMHI, which covers female children age 2-3, is one of six summary recodes for CBCL questions.
The other variables in this series are the following:
Before asking the appropriate set of questions for female sample children age 2-3, the interviewer stated, "I am going to read a list of items that describe children. For each one, tell me if it has been NOT TRUE, SOMETIMES TRUE, or OFTEN TRUE, of [sample child] during the past 2 months."
The Field Representative's Manuals for 1997-2000 instructed interviewers, "[i]f the respondent gives an answer which does not match the categories read in the question, reread the question emphasizing the wording of the answer categories."
The statements parents were asked to rate for female sample children age 2 to 3 included:
- Has temper tantrums or a hot temper?
- Has speech problems?
- Has been nervous or high-strung?
- Has been unhappy, sad, or depressed?
Responses for these four items were coded by NHIS as 0 (Not True), 1 (Sometimes True), and 2 (Often True). Individual item scores were then summed to calculate an overall MHI score ranging from 0 (lowest need for mental health services) to 8 (highest need for mental health services), which is reported in FTODMHI.
The 1997-2000 NHIS Survey Descriptions provide the following explanation for how items were chosen from the Child Behavior Checklist for use in the NHIS:
The items selected from the CBCL for parents to rate for the other gender/age groups (other than females age 2-3) included:
- Has been uncooperative?
- Has trouble getting to sleep?
- Has speech problems?
- Has been unhappy, sad, or depressed?
- Doesn't get along with other kids?
- Can't concentrate or pay attention long?
- Feels worthless or inferior?
- Has been unhappy, sad, or depressed?
- Can't concentrate or pay attention long?
- Has been nervous, high strung or tense?
- Acts too young for her age?
- Has been unhappy, sad, or depressed?
- Can't concentrate or pay attention long?
- Lies or cheats?
- Doesn't get along with other kids?
- Has been unhappy, sad, or depressed?
- Lies or cheats?
- Does poorly at school work?
- Has trouble sleeping?
- Has been unhappy, sad, or depressed?
Scores for the individual subscale items were only made publicly available for "Has been unhappy, sad, or depressed?" (Males and Females 2-3, TODDEPRES; Males and Females 4-11, KIDDEPRES; Males and Females 12-17, TEENDEPRES).
Data analyses specified and reviewed by Dr. Achenbach were conducted at the National Center for Health Statistics (NCHS) using data from the 1997 NHIS. According to the Codebooks of the NHIS public use files for 1997-forward, these analyses included "tabulations of specific responses to each behavior/emotional problem item" as well as "tabulations of relations between total problem scores and classification of children as deviant versus nondeviant on the basis of external criteria."
Examples of such "external criteria" included the parent's affirmative response to the following questions:
- Attention Deficit Disorder? (ADDEV)
- Mental Retardation? (RETEV)
- Any other developmental delay?(ODDEV)
- Down's syndrome? (DOWNSYNEV)
- Autism? (AUTISMEV)
- Mental health care or counseling? (YBARMENTAL)
- A mental health professional such as a psychologist, psychiatric nurse, or clinical social worker? (SAWMENT)
Relative Operating Characteristic (ROC) analyses were then performed on the overall MHI scores to ascertain the sensitivity and specificity of different cutpoints in predicting the likelihood of a "deviant" classification.
According to the Codebooks for 1997-forward, Dr. Achenbach made the following recommendation for sample children age 2-3 based on the analyses conducted at NCHS:
- The total number of children . . . classified as deviant according to external criteria . . . was too small to provide a sound basis for establishing cutpoints;
- Many disorders relevant to defining criterion groups (e.g., ADHD) are not identified as early as age 2-3;
- The rates of referral for mental health services and other possible indicators of deviance are much lower at ages 2-3 than at older ages.
The Codebooks for 1997-forward also include the following cautionary note regarding the interpretation of MHI scores:
Comparability
FTODMHI is completely comparable over time.
For 2001 forward, the NHIS replaced the CBCL questions for children age 4-17 with the Strengths and Difficulties Questionnaire (SDQ), but retained the CBCL questions for children age 2-3. For more information on the SDQ, see any of the Child Strengths and Difficulties variables (e.g., BADTEMPER).
