Abstract: According to PAC theory, the problems in the horizontal communication ability of visually impaired teenagers are mainly reflected in problems in non-parallel communication, cross-communication and hidden communication. The lack of horizontal communication ability of visually impaired teenagers is mainly due to the absence of A state in self-state orientation, lack of recognition and cognitive disorder in communication, and the rigidity and degeneration of the central structure of self-state transformation. According to PAC theory, to improve the horizontal communication ability of visually impaired teenagers, social workers can start from the following aspects: psychological empowerment based on A-A communication mode, training and situational simulation based on PAC theory, and practical reconstruction based on PAC theory.

Key words: social worker intervention, PAC theory, visually impaired teenager, horizontal communication ability
