These obstacles include parents underreporting behavioral and emotional problems, the requirements that office visits be brief, insurance restrictions, and a lack of available child mental health specialists, thus delaying referrals, according to Kelleher. More than two-thirds of primary care clinicians who pursue a referral for a child patient report encountering appointment delays, with average time to appointment with a specialist being three to four months. Of those patients who were referred, 59 percent had no visits to the specialist; only 13 percent averaged one or more visits a month in the follow-up period of six months. In short, an increasing number of problems (15 percent to 30 percent) are being identified by primary care providers, but rates of recognition (48 percent to 57 percent) are still low, and connections to mental health specialists are difficult.
