METHODOLOGY 



James H. LeFan and Robert Helmreich 

 The University of Texas at Austin 



Data collection was conducted in four ways: (1) pre-mission testing; (2) con- 

 tinuous observation of in-habitat behavior; (3) self-report questionnaires 

 filled out daily by aquanauts during their dive; and (4) structured debriefing 

 of aquanauts immediately after decompression. 



Pre-Mission Testing 



After arrival at the base camp, each aquanaut was given a complete briefing on 

 the scope and goals of the Behavior Program. The nature of data to be collected 

 and provisions to ensure the confidentiality of all responses were explained. 

 Following the briefing, each aquanaut completed a battery of demographic and 

 personality measures. These measures are listed in Table 1. The major pre- 

 mission measure was the Life History Questionnaire. Its theoretical importance 

 is such that it is described in detail later in this section. Variables from 

 these instrimients are used both to describe the aquanaut population and to pre- 

 dict performance and adjustment during missions. 



Behavioral Observations During Missions 



The major source of data during TEKTITE II was the direct observation of aqua- 

 nauts 24 hours a day during their life in the underwater habitat. These data 

 were collected by three teams of male observers from the University of Texas at 

 Austin. Each team served on site for approximately 1\ months. Team 1 had 

 eight observers; Team 2, ten (augmented to collect data on the aborted minitat 

 missions); and Team 3, eight. Observers were undergraduate or graduate students
