Organizational Network Analysis of SAMHSA's Technology Transfer Center (TTC) Network

Area of Science:

• Behavioral Health
• Public Health Networks
• Organizational Science

Background:

• Technology transfer centers (TTCs) are crucial for disseminating evidence-based practices in behavioral healthcare.
• The Substance Abuse and Mental Health Services Administration (SAMHSA) operates a large TTC Network.
• Evaluating the structure and effectiveness of such networks is vital for optimizing support systems.

Purpose of the Study:

• To conduct an organizational network analysis (ONA) of the SAMHSA TTC Network.
• To identify network density, centrality, and reciprocity among TTCs.
• To compare network characteristics of standalone versus multiple-TTC grantees.

Main Methods:

• Organizational network analysis (ONA) was applied to 36 non-supervisory TTCs.
• Network metrics including density, harmonic closeness, and dyadic reciprocity were computed for five interaction types.
• Welch's T-test compared harmonic closeness between standalone and multiple-TTC grantees.

Main Results:

• ONA identified potentially isolated regional TTCs within the network.
• Mismatches were observed between TTCs' intended scope and their actual network centrality.
• Significant differences in harmonic closeness were found between standalone and multiple-TTC grantees for specific interaction types.

Conclusions:

• Organizational network analysis is a valuable tool for evaluating TTCs and similar support networks.
• The findings highlight areas for potential network improvement and targeted support.
• Understanding network structures can enhance the dissemination of behavioral health practices.
