& Seid, 2009; Mechling & Gustafs<strong>on</strong>, 2008); a<br />

resource room <strong>and</strong> grocery store (Cihak, Alberto,<br />

Taber-Doughty, & Gama, 2006); a community<br />

house (Ti<strong>on</strong>g, Blampied, & le Grice,<br />

1992); the laundry room in a group home<br />

(Horn et al., 2008); the kitchen of a vocati<strong>on</strong>al<br />

training center (Cannella-Mal<strong>on</strong>e et al., 2006;<br />

Goods<strong>on</strong>, Sigafoos, O’ Reilly, Cannella, &<br />

Lanci<strong>on</strong>i, 2007; Sigafoos et al., 2007; Sigafoos<br />

et al., 2005); an apartment kitchen (Mechling,<br />

Gast, & Fields, 2008; Mechling & Gustafs<strong>on</strong>,<br />

2009; Mechling & Stephens, 2009); <strong>and</strong> an<br />

animal shelter (Van Laarhoven, Johns<strong>on</strong>, Van<br />

Laarhoven-Myers, Grider, & Grider, 2009).<br />

Overall, most studies were c<strong>on</strong>ducted in<br />

kitchen or home living settings because they<br />

involved cooking-related tasks.<br />

Designs<br />

Researchers in the majority of the studies used<br />

a multiple baseline/multiple-probe design<br />

across behaviors/participants (Graves et al.,<br />

2005; Horn et al., 2008; Mechling et al., 2003;<br />

Mechling et al., 2008; Mechling et al., 2009;<br />

Norman et al., 2001; Ti<strong>on</strong>g et al., 1992; Van<br />

Laarhoven et al., 2009). However, in some<br />

studies a multiple-baseline design was combined<br />

with an alternating treatment or ABAB<br />

design: ABAB combined with multiple-baseline<br />

across participants (Goods<strong>on</strong> et al., 2007;<br />

Sigafoos et al., 2007; Sigafoos et al., 2005); a<br />

multiple-probe across participants with an alternating<br />

treatment design (Cannella-Mal<strong>on</strong>e<br />

et al., 2006). An adapted alternating treatments<br />

design was used in five studies (Cihak et<br />

al., 2006; Mechling & Gustafs<strong>on</strong>, 2008, 2009;<br />

Mechling & Stephens, 2009; Van Laarhoven &<br />

Van Laarhoven-Myers, 2006). In <strong>on</strong>e study an<br />

AB design was replicated across participants<br />

(Grice & Blampied, 1994).<br />

Targeted Skills<br />

Researchers in several studies (n 7) targeted<br />

food preparati<strong>on</strong> or cooking-related skills<br />

(Graves et al., 2005; Mechling et al., 2008;<br />

Mechling et al., 2009; Mechling & Gustafs<strong>on</strong>,<br />

2008, 2009; Mechling & Stephens, 2009; Sigafoos<br />

et al., 2005) <strong>and</strong> in <strong>on</strong>e study cooking<br />

tasks (such as microwaving pizza) were combined<br />

with other tasks such as washing a table<br />

<strong>and</strong> folding laundry (Van Laarhoven & Van<br />

Laarhoven-Myers, 2006). Investigators targeted<br />

self-help skills <strong>and</strong>/or other daily living<br />

skills in a number of studies, such as: purchasing<br />

<strong>and</strong> banking skills (Cihak et al., 2006;<br />

Mechling et al., 2003), table setting (Goods<strong>on</strong><br />

et al., 2007), setting the table <strong>and</strong> putting away<br />

groceries (Cannella-Mal<strong>on</strong>e et al., 2006), doing<br />

laundry (Horn et al., 2008), dish washing<br />

(Sigafoos et al., 2007), cleaning sunglasses,<br />

putting <strong>on</strong> a wristwatch, <strong>and</strong> zipping a jacket<br />

(Norman et al., 2001). In a few of the studies<br />

investigators targeted other skills, such as operating<br />

video <strong>and</strong> computer devices (Grice &<br />

Blampied, 1994); job-related tasks including<br />

cleaning a bathroom, mopping floors, taking<br />

out garbage, <strong>and</strong> cleaning kennels at an animal<br />

shelter (Van Laarhoven et al., 2009); <strong>and</strong><br />

safely exiting bedrooms in the event of fire<br />

(Ti<strong>on</strong>g et al., 1992). Overall, a majority of the<br />

tasks involved cooking <strong>and</strong> self-care/independent<br />

living skills.<br />

Video Prompting Material<br />

Types of video prompts. The video prompts<br />

were mainly c<strong>on</strong>sistent across the studies.<br />

Video prompts were prepared either from the<br />

participant’s viewpoint or spectator’s viewpoint.<br />

A majority of the videos were prepared<br />

from the spectators’ viewpoint with verbal or<br />

voice-over instructi<strong>on</strong>s (Goods<strong>on</strong> et al., 2007;<br />

Grice & Blampied, 1994; Mechling et al.,<br />

2009; Mechling & Gustafs<strong>on</strong>, 2008, 2009;<br />

Mechling & Stephens, 2009; Ti<strong>on</strong>g et al.,<br />

1992; Van Laarhoven et al., 2009). In <strong>on</strong>e<br />

study, the investigators menti<strong>on</strong>ed that the<br />

videos were prepared from the spectators’<br />

viewpoint (Van Laarhoven & Van Laarhoven-<br />

Myers, 2006); however, they did not menti<strong>on</strong><br />

whether any verbal instructi<strong>on</strong>s were used in<br />

the video prompt. Researchers in several<br />

other studies used video prompts from the<br />

participants’ viewpoint or with other combinati<strong>on</strong>s,<br />

including: participants’ viewpoint with<br />

voice-over instructi<strong>on</strong>s (Cannella-Mal<strong>on</strong>e et<br />

al., 2006; Graves et al., 2005; Sigafoos et al.,<br />

2007; Sigafoos et al., 2005), participants’ viewpoint<br />

with voice-over instructi<strong>on</strong>s <strong>and</strong> text display<br />

(Norman et al., 2001), participant’s viewpoint<br />

(Horn et al., 2008), <strong>and</strong> participants’<br />

<strong>and</strong> spectators’ viewpoint with voice-over instructi<strong>on</strong>s<br />

(Mechling et al., 2008).<br />
