referring now to the drawing where like reference numerals refer to like parts there is shown at 20 in fig1 a system constructed in accordance with this invention to produce a specific customized or tailored plan to an individual wishing to modify , e . g ., stop , an undesirable health - related behavior or to maintain a desirable health - related behavior . the system is particularly suited for facilitating smoking cessation , weight reduction , stress control , or other health - related behaviors . to achieve that end the system produces and provides a series of customized daily messages 30 to be followed by the individual for whom the plan is designed . the plan is custom developed for the individual in accordance with personal information provided by the individual . it should be pointed out at this juncture that the system shown in fig1 is generalized since it can be used for any type of health - related behavior modification / maintenance based on information provided by the individual . thus , fig1 shows various ways that personal information data about an individual for whom the plan is to be developed is provided into the system , as well as various ways the data can be communicated to a system computer for processing and various ways the plan &# 39 ; s messages 30 can be delivered to the individual . in short , the system 20 shown in fig1 is merely exemplary and other systems can be constructed in accordance with this invention . in accordance with one preferred methodology of this invention , before the customized plan is developed a &# 34 ; preparatory phase &# 34 ; is conducted . the preparatory phase is shown in the block diagram of fig2 and basically consists of providing the potential user of the plan introductory information which is specific to the particular health - related behavior to be altered or maintained . for example , if the health - related behavior is smoking , the individual is provided with specific introductory information relating to smoking . preferably , that information is differentiated to the individual &# 39 ; s particular situation , e . g ., teen smokers , pregnant smokers , heavy smokers , etc . this preparatory information can be provided to the individual by any suitable means , e . g ., a personal interview or a group session , mail , the internet , e - mail and facsimile . after the preparatory phase has been completed , the &# 34 ; personal collection phase &# 34 ; of the plan is undertaken . in that phase questions are communicated to the individual to gather personal information from him / her to customize or tailor the plan so that it has its greatest chance of success . the questions for the individual may be of the type utilized in the aforementioned strecher patent or any others deemed suitable . those questions can be communicated to the individual by any suitable means , such as a personal interview , a telephonic interview , facsimile , or a printed questionnaire . if the individual has his / her own computer system 22 ( fig1 ), the questionnaire may be provided via e - mail or an internet web site . alternatively , the individual may be provided with a personal computer program disk or cd to run on his / her computer to provide the questions . if the person has a facsimile machine the questions can be provided via that machine . the individual &# 39 ; s answers to the questions of the questionnaire may be provided into the system 20 via any suitable means , e . g ., personal interview , telephonic interview , access to an internet web site , e - mail , facsimile or return of an answered printed questionnaire . irrespective of the manner in which the questions are presented to the individual and or the manner that his / her answers are provided back for use in the system , the answers form as what is identified as &# 34 ; questionnaire data &# 34 ; shown in block diagram in fig3 . it is this questionnaire data which the system 20 uses to develop the tailored plan for the individual . in particular , the system 20 includes a computer 24 into which the questionnaire data is input . that data may be entered into the computer 24 via keyboard entry , telephonic connection , or any other suitable means , e . g ., voice recognition software , etc . the inputting of the personal information data into the computer 24 starts the &# 34 ; personal plan generation phase &# 34 ; of the subject invention . in accordance with one preferred aspect of this invention , the computer 24 preferably makes use of &# 34 ; expert system &# 34 ; software to establish the algorithms for processing the questionnaire data into a smoking cessation plan specifically designed and developed for the individual . the plan produced by the system 20 is arranged to be communicated to the individual by means of the series of daily messages 30 in the form of coherent narrative instructions , divided into non - dated daily sections for the individual to follow . the messages are preferably in hard copy form , e . g ., printed sheets or cards 30 ( fig1 ). the sheets or cards 30 may be communicated or delivered to the individual in any suitable way . for example , they may be printed out by a printer 26 associated with the system computer 24 and then mailed or otherwise delivered to the individual . if the individual has a computer system with a printer , the messages may be delivered electronically , e . g ., via the internet , e - mail , facsimile , etc ., to the individual . while it is preferable that the messages ultimately be reduced to hard copy form ( e . g ., a series of cards or sheets , like those to be described later ) the messages may be transient or stored electronically so that they only appear on the video monitor associated with the individual &# 39 ; s computer 22 . in any case and in accordance with the preferred embodiment of this invention , each of the daily messages 30 includes coherent narrative instructions relevant to the particular day of the plan , that is a series of instructions for the &# 34 ; first &# 34 ; day , the &# 34 ; second &# 34 ; day , the &# 34 ; third &# 34 ; day , etc . moreover , as can be seen in fig1 and 3 , each of the daily messages 30 bears indicia 32 on it indicating the relative day of the plan . thus , the first day of the plan is identified as &# 34 ; day 1 &# 34 ; and is the day that the individual chooses to start the plan . that day can be any calendar date chosen by the individual , i . e ., the starting date of the plan is not predetermined or preestablished to be a particular day . thus , each of the daily messages 30 is non - dated . by non - dated it is meant that each message does not have any calendar date thereon so that the individual is not tied to any particular calendar date for any particular activity as part of the plan . as mentioned earlier by associating a particular calendar date to a particular activity ( e . g ., june 9 th being the &# 34 ; quit &# 34 ; or start day for the plan ) if the user should miss that date , he or she may try to catch up to get back in synchronism , thereby detracting from the efficacy of the plan or dooming it to failure . in fig3 the daily sheets or cards 30 produced in accordance with this plan are illustrated in grossly simplified form in the interest of drawing simplicity . thus , as can be seen the series of sheets / cards 30 include a first sheet or card 30a having a front side and a rear or back side . the next consecutive sheet or card is the &# 34 ; day 1 &# 34 ; sheet or card 30b . it too includes a front side and a back side . the next successive card is the &# 34 ; day 2 &# 34 ; card 30c which has a front side and a back side . in accordance with one exemplary embodiment the smoking cessation plan is of a duration of twenty - one days . thus , the last of the daily cards or messages is identified as the &# 34 ; day 21 &# 34 ; card 30v . if desired , additional cards ( not shown ) may be provided in the form of &# 34 ; maintenance instruction &# 34 ; cards . as can be seen in fig1 and 5 the front side of each card bears indicia 32 indicating of the day of the plan . the front side also includes indicia 34 bearing the narrative instructions for the regimen of that day . on the reverse or back side of each sheet or card 30 there is indicia 36 bearing information which is relevant to the type of behavior at issue , but which is generalized and not particularly tailored for the individual . the narrative instructions 34 which appear on the front side of each of the cards / sheets 30 and which have been customized for the individual include a sufficient amount of material in coherent narrative form to provide substantial guidance for the individual to follow that day . it is preferred that the individual be provided with a sheet or card for each day of the plan on the day for that card so that he / she is not be exposed to any of the cards or sheets for subsequent days of the plan in order to avoid overwhelming him / her with excessive information and distracting him / her with prematurely disclosed later stage instructions . to that end , if the cards or sheets are delivered electronically via the internet , facsimile , e - mail , etc ., they are preferably delivered one at a time , each day of the plan . if all the sheets or cards for the plan are delivered at one time , the individual is preferably instructed to only look and follow the instructions and information on the sheet or card 30 for that particular day of the plan . turning now to fig3 and 4 , the details of two exemplary sheets or cards 30 will be described . thus , as can be seen the first sheet or card 30 of the series , that is sheet or card 30a , is in the form of a &# 34 ; personal profile &# 34 ; card . to that end it includes a concise summarization of the personal profile of the individual on which the personal plan was based from the questionnaire answers . as can be seen in fig4 the front side of the personal profile card 30a for an exemplary individual , &# 34 ; john doe ,&# 34 ; indicates that mr . doe &# 39 ; s age is 53 , he is a male and there is one other smoker in his household . mr . doe smokes an average of 20 cigarettes a day . he has tried to quit three times . the longest period he has not smoked has been 31 / 2 months . his last attempt to quit was in june 1979 . he has tried nicotine replacement products , such as patch and gum . he smokes within 30 minutes of rising . he smokes for pleasure , stress relief and self - reward . he wants to quit for health concerns and pressure from his family . he fears gaining weight and lack of will - power as a barrier to his quitting . he believes his smoking habit is triggered as an after meal ritual or when he is driving or in a stressful situation or when he consumes alcohol . he is somewhat confident about his chances of success in quitting smoking . as mentioned above all of the information appearing on the front side of the personal profile sheet or card 30a is derived from the answers to the questions presented to mr . doe during the personal data collection phase . the reverse side of the card 30a includes general information about smoking cessation for mr . doe &# 39 ; s general guidance or information and has not been specifically tailored for him . the next card or sheet 30 of the series of messages is the heretofore identified &# 34 ; day 1 &# 34 ; card or sheet 30b . this card or sheet is shown in detail in fig5 and constitutes the first day of the plan . thus , the indicia 32 appearing on the front side of the card 30b bears the indicia &# 34 ; day 1 .&# 34 ; this day is mr . doe &# 39 ; s &# 34 ; quit day .&# 34 ; in addition the day 1 card 30b bears detailed instructions in the form of indicia 34 on the front side of the card . these instructions are to be followed by john doe on whatever day he decides should be &# 34 ; day 1 &# 34 ; or the &# 34 ; quit day &# 34 ; of his plan . in the exemplary embodiment in fig5 the &# 34 ; day 1 &# 34 ; card of the plan focuses on mr . doe &# 39 ; s specific concerns about gaining weight and lacking willpower . the reverse or back side of the &# 34 ; day 1 &# 34 ; card 30b includes a series of instructions which are generally applicable to those desiring to quit smoking , e . g ., for mr . doe to get rid of all smoking materials . specifically , mr . doe is advised to destroy all cigarettes and remove all ashtrays , lighters and matches from his home , workplace and car . by following the recommendations appearing on the front and back side ofthe &# 34 ; day 1 &# 34 ; card , mr . doe will be on his way to breaking his habit of smoking . on the next successive day , mr . doe will read and follow the &# 34 ; day 2 &# 34 ; card 30b , and in particular its tailored instructions 34 and its generalized information 36 appearing on the front and back of the card , respectively . on the third day of the plan mr . doe will direct his attention to the &# 34 ; day 3 &# 34 ; card to follow the regimen presented thereby . this procedure is to be followed by mr . doe for each successive day of the plan through &# 34 ; day 21 ,&# 34 ; at which point mr . doe should have broken his habit of smoking . at this point mr . doe can be provided with detailed maintenance instructions . those instructions can be in the form of additional cards or sheets ( not shown ) or may be messages delivered by some electronic communication means , such as facsimile , e - mail , etc . if appropriate , instructions can be provided by personal contact , a telephone conversation , regular mail , etc . in accordance with another preferred aspect of this invention , a computer generated follow - up can be provided to mr . doe , via the internet , e - mail , facsimile , personal contact , or some other means . the follow - up is provided to determine how well mr . doe has done in accomplishing his goal of quitting smoking . if any additional assistance is necessary it can be provided to him in any suitable manner . as mentioned above the &# 34 ; personal profile &# 34 ; of the individual is established by his / her answers to the questionnaire , and serves as a basis for the development of the customized regimen or plan produced for that individual by the system of the subject invention . in some applications , it may be desirable to enable the individual to provide the system with updated personal information so that his / her personal profile may be modified or adjusted during the days making up the plan in order to more closely tailor the plan to him / her . the implementation of such modifications / adjustments to the plan can be readily accomplished in various ways . for example , if the system of the subject invention is connected to the internet and a web - site is provided , the person may be given a personal identification number ( pin ) to gain access to that web - site , where he / she could provide updated personal information about himself / herself . the system &# 39 ; s computer in conjunction with the expert system software will then operate on that information to update the personal profile and generate succeeding messages based on the updated profile . these updated messages are preferably be provided back to the person immediately , e . g ., while the person is still at the web - site . alternatively , the modified or adjusted messages may be delivered in any other suitable manner or at any suitable time by any means , e . g ., like those discussed earlier with respect to the unmodified messages . the following constitutes one exemplary procedure in a smoking cessation program to provide a person , john doe , with messages which are adjusted or modified in accordance with updated information provided by him / her to the system of this invention . during the course of the 21 - day program , john doe receives cards / sheets as discussed above and which reflect his initial personal profile ( i . e ., the personal profile developed in response to his answers to the questionnaire ). however , using any suitable electronic communication media , e . g ., the internet , john doe has the option of daily opportunities to edit his personal profile . thus , each day he can access the system , e . g ., visit and log onto the web - site , and respond to further questions designed specifically for someone of his profile at that specific point in time . based on the john doe &# 39 ; s responses , the expert software of the system designs a set of instructions for the next 24 hours and prompts him to check - in tomorrow and &# 34 ; let us know how you are doing .&# 34 ; if , for example , if it &# 39 ; s the 11 th day (&# 34 ; day 11 &# 34 ;) of the plan and john doe is having a particularly difficult time dealing with anger / stress and he provides that information to the system when he has logged into the web - site , the system will adjust the 12 th day (&# 34 ; day 12 &# 34 ;) message accordingly . thus , the day 12 message will include not only the standard instructions for that day , but also helpful hints on how john doe can handle stressful situations without a cigarette . as should be appreciated by those skilled in the art of health - related behavior modification techniques , the ability to modify or adjust a health - related behavior plan as it is being carried out ( on - the - fly ) is a powerful feature , since it mimics what would typically occur in a person - to - person intervention program . another factor that can have critical importance to a successful change process is the amount and quality of external support provided to the individual . for example , a sensitive and informed support network can greatly enhance the likelihood that positive behavior change is initiated and , more importantly , sustained . while there is a great deal of information that targets individuals seeking change , very little exists on how to be a support person . all to often , the process is approached intellectually , such as presenting logical information to the person in the hope he / she will see the wisdom of the information and simply change . this may be called the &# 34 ; do - the - right - thing &# 34 ; approach . while logical , it denies the psychological , sociological , and physiological complexity of lifestyles . thus , using the &# 34 ; do - the - right - thing &# 34 ; approach by brow - beating an individual desiring to effect a change in his / her behavior with facts , logic , and emotional blackmail ( e . g ., a loved - one stating &# 34 ; if you really love me , you &# 39 ; ll change &# 34 ;) is likely to be counter - productive , since it often triggers reactions of guilt , anger , and fear in the individual . the need to escape from these feelings often leads the individual directly to the very health - related behavior which is attempted to be modified or ended ( e . g ., smoking , excessive drinking , drug abuse , sedentary lifestyle , etc .). taking the foregoing into account , the system and method of the subject invention may be implemented by encouraging and educating another person / persons with whom the individual wishing to change his / her health - related behavior has a close , personal relationship . this other person ( s ) is deemed to be a &# 34 ; lifestyle coach &# 34 ; and will have on - going access to the system 20 , the plan or regimen developed for the individual , and to &# 34 ; coaching information .&# 34 ; the coaching information is tailored to help the coach understand the chronological process of change and offer interactive opportunities to improve the quality of his / her coaching for the individual . to that end , in accordance with one preferred aspect the of this invention the system 20 is arranged to develop a tailored reference coaching plan which will correlate directly with the tailored program being used by the individual wishing to change his / her behavior . the tailored coaching plan can be developed through use of a questionnaire or any suitable means and is preferably provided to the coach in the form of daily messages , correlated to those provided to the individual undergoing the behavior - change process . for example , if john doe , is in any day ( e . g ., &# 34 ; day 4 &# 34 ;) of his smoking cessation program , his coach may receive a tailored message that deals specifically with the concerns associated with that day . these daily messages may be delivered to the coach in any suitable manner ( e . g ., through internet access ). each message bears indicia indicating the day of the plan , e . g ., &# 34 ; day 4 ,&# 34 ; blocks of generic textual information relating generally to the behavior in issue , as well as specific or tailored information for the coach to make use of in assisting john doe to break the smoking habit . in fact , the system 20 is designed so that the coach can query the expert system software for additional tips , as well as respond to a series of questions designed to determine or measure how well he / she is responding to specific challenges in coaching the individual . as discussed earlier the expert system software has within it the interest profile of the individual desiring to modify his / her health - related behavior ( the profile having been developed by the system in response to the individual &# 39 ; s answers to a questionnaire ). preferably , the interest profile of each coach will also be resident in the system and will have been developed by the expert system software in response to a questionnaire answered by the coach or from information gathered from the coach in some other manner . the use of the profiles of both the individual undergoing the behavior modification and his / her coach enables the system 20 to provide the coach with messages which enable him / her to better support the individual &# 39 ; s efforts . for example , to aid john doe &# 39 ; s coach in helping john doe to stop smoking , a message his coach may receive on one day may read : &# 34 ; because john doe enjoys bowling , as do you , you may suggest that the two of you go to the local alley , bowl a couple of games , and enjoy your time together .&# 34 ; as mentioned earlier the system 20 is designed to also capture up - to - the - minute information from the individual undergoing the health - related behavior modification to modify his / her plan &# 34 ; on - the - fly .&# 34 ; to further facilitate such plan modification ( s ), the system 20 is preferably arranged to advise the coach of any changes or modifications to the plan resulting from the daily input of the individual . these daily change notices are provided to the coach in the messages provided to him / her . it must be reiterated at this juncture that the subject system and methodology has wide applicability , and thus is not limited to smoking cessation plans . thus , it can be used to modify any undesirable behavior . moreover , it can be used to establish a plan for maintaining a desired behavior , e . g ., it can be used to help a person who has already quit smoking to maintain that behavior , to aid a person who has lost weight to keep the weight off , etc . in fact , the subject system and method can be used in any application calling for habitual behavior modification and / or maintenance , whether or not health related . without further elaboration the foregoing will so fully illustrate my invention that others may , by applying current or future knowledge , adopt the same for use under various conditions of service .
